The price of one packet of instant noodles can be determined by finding the difference in the total prices paid by Ibu A and Ibu B for the same number of packets of instant noodles. By subtracting the total price paid by Ibu B from the total price paid by Ibu A, we get Rp 10,700 - Rp 14,900 = -Rp 4,200. Since Ibu A paid more than Ibu B, the negative value indicates that the price of one packet of instant noodles is lower for Ibu B. The difference in the number of packets bought by Ibu A and Ibu B is 4 - 3 = 1 packet. Therefore, the price of one packet of instant noodles is Rp 4,200 divided by 1, which is Rp 4,200. Answer: Rp 800,-.

The given system of equations can be solved using the method of substitution or elimination. By subtracting the second equation from the first equation, we can eliminate the variable y and solve for x. The resulting equation is x = 4. Substituting this value of x into either of the original equations, we can solve for y. In this case, substituting x = 4 into the second equation gives us 2(4) + 5y = 23, which simplifies to 8 + 5y = 23. Solving for y, we get y = 3. Therefore, the values of x and y are 4 and 3 respectively.

The question states that the father is currently 24 years older than the child. Two years ago, the father's age was 4 times the age of the child. By subtracting 2 years from the current age of the father, we can find the age of the child at that time. Then, by dividing the father's age at that time by 4, we can find the age of the child. Therefore, the current age of the child is 10 years.

Seven years ago, the age of the father was equal to 6 times the age of Budi. This can be represented as (A-7) = 6(B-7), where A represents the current age of the father and B represents the current age of Budi. Four years from now, 2 times the age of the father will be equal to 5 times the age of Budi plus 9 years. This can be represented as (A+4)*2 = 5(B+4) + 9. By solving these equations simultaneously, we can find that the current age of the father is 43.

The supervisor received a total honor of Rp 62,400.

Let's assume the first number is x and the second number is y. According to the given information, 2x + 4y = 40. We also know that x is twice as much as y, so we can write x = 2y. Substituting this value in the first equation, we get 2(2y) + 4y = 40. Simplifying this equation, we get 4y + 4y = 40, which gives us 8y = 40. Dividing both sides by 8, we find y = 5. Since x = 2y, x = 2(5) = 10. Therefore, the value of the first number is 10.

The total revenue from selling 600 tickets of class I and 450 tickets of the balcony class is Rp. 4,500,000. Let's assume the ticket price of class I is x. According to the given information, the ticket price of the balcony class is 1/3 of the ticket price of class I, which means it is x/3.

So, the equation can be formed as follows:
600x + 450(x/3) = 4,500,000

To solve this equation, we can simplify it by multiplying both sides by 3 to eliminate the fraction:
1800x + 450x = 13,500,000
2250x = 13,500,000
x = 6,000

Therefore, the ticket price of class I is Rp. 6,000.

The given equation is 323x - 19y = 133. To find the value of -187x + 11y, we need to substitute the value of x and y from the given equation. By rearranging the equation, we can find the value of x in terms of y, which is x = (133 + 19y)/323. Substituting this value of x in -187x + 11y, we get (-187(133 + 19y)/323) + 11y. Simplifying this expression gives us -77, which is the correct answer.

Based on the given information, we know that the total amount of money Amir, Budi, and Hasan have is Rp. 100,000. We also know that the difference between Budi and Hasan's money is Rp. 5,000. Additionally, Amir's money is Rp. 20,000 more than Budi's money plus two times Hasan's money. Therefore, we can calculate Budi's money by subtracting Rp. 5,000 from the total amount (Rp. 100,000 - Rp. 5,000 = Rp. 95,000). Since Amir's money is Rp. 20,000 more than Budi's money plus two times Hasan's money, we can deduce that Amir's money is Rp. 95,000 + (2 x Hasan's money). By substituting the given information, we find that Amir's money is Rp. 67,000.

In 2002, the age of the child is equal to one-fourth of the mother's age. Let's assume the child's age in 2002 is x and the mother's age is y. So, we have the equation x = (1/4)y. In 2006, the child's age is one-third of the mother's age. Let's assume the child's age in 2006 is a and the mother's age is b. So, we have the equation a = (1/3)b. From these two equations, we can solve for y and b. By substituting the values of y and b into the equation x = (1/4)y, we can find the child's age in 2002. The correct answer is 1994.

The given information provides the prices of different quantities of fruits. By comparing the prices of different combinations, we can determine the individual prices of each fruit. From the given information, we can calculate that the price of 2 kg of mangoes is Rp 20,000, the price of 2 kg of oranges is Rp 30,000, and the price of 3 kg of grapes is Rp 40,000. To find the price of 1 kg of oranges, we can subtract the prices of mangoes and grapes from the total price of the combination, which is Rp 70,000. Therefore, the price of 1 kg of oranges is Rp 10,000.

The given information provides a system of equations to solve for the prices of the fruits. Let's assume the prices of 1 kg of mango, 1 kg of orange, and 1 kg of grapes are represented by x, y, and z respectively. From the first equation, we can write 2x + 2y + z = 70000. From the second equation, we can write x + 2y + 2z = 90000. From the third equation, we can write 2x + 2y + 3z = 130000. By solving these equations, we find that x = 10000. Therefore, the price of 1 kg of orange is Rp 10.000,00.

The given information states that the price of bricks in Sumatra is $500 per ton for the first 12 tons, and $500 minus x for any amount purchased above 12 tons. The question asks for the value of x if the purchase of 30 tons of bricks is worth $13,650. To solve this, we can set up an equation: 12 tons * $500 + (30 tons - 12 tons) * ($500 - x) = $13,650. Simplifying this equation will give us x = 45.

The given information states that it costs Rp 1,000,000 to print the first 1000 books and x rupiah per book for any additional books above 1000. The total cost of printing 8000 books is Rp 7,230,000. To find the value of x, we need to subtract the cost of printing the first 1000 books from the total cost and then divide the remaining cost by the number of additional books (8000 - 1000 = 7000). Therefore, x = (7,230,000 - 1,000,000) / 7000 = Rp 890.

The correct answer is 45 and 50 because if Ajo has Rp 3 million in savings and part of it receives a 10% interest rate per year and the rest receives an 8% interest rate per year, the total interest he receives is Rp 256,000. To find out how much money Ajo has in the bank with an 8% interest rate, we can set up the equation: 0.1x + 0.08(3,000,000 - x) = 256,000. Solving this equation, we find that x = 450,000, which means Ajo has Rp 450,000 in the bank with an 8% interest rate. Therefore, the answer is 45 and 50.

When the bus is filled with 36 people, the cost per person increases by Rp. 12,000 compared to when it is filled with 40 people. This means that the additional cost for the 4 extra people is Rp. 12,000. Therefore, the cost per person when the bus is filled with 40 people can be calculated by subtracting Rp. 12,000 from the cost per person when the bus is filled with 36 people. So, if the cost per person when the bus is filled with 36 people is Rp. 120,000, then the cost per person when the bus is filled with 40 people would be Rp. 120,000 - Rp. 12,000 = Rp. 108,000.

Ajo memerlukan waktu 30 detik per lantai untuk turun dengan tangga dan 2 detik per lantai untuk turun dengan elevator. Jika waktu yang diperlukan untuk turun dengan tangga sama dengan waktu yang diperlukan untuk menunggu elevator selama 7 menit (420 detik) dan turun dengan elevator, maka waktu yang diperlukan untuk menuruni tangga adalah 420 detik. Jika Ajo tinggal x lantai di atas lantai dasar, maka waktu yang diperlukan untuk menuruni tangga adalah 30x detik. Oleh karena itu, 30x = 420, sehingga x = 14. Namun, pertanyaan menanyakan berapa lantai di atas lantai dasar, bukan berapa lantai di bawah lantai dasar. Jadi, jumlah lantai di atas lantai dasar adalah 14 + 1 = 15.

If x = y = 2z and x.y.z = 256, then we can substitute y and z in terms of x. Since x = y = 2z, we can substitute y = x and z = x/2. Plugging these values into the equation x.y.z = 256, we get x * x * (x/2) = 256. Simplifying this equation, we get x^3/2 = 256. Taking the cube root of both sides, we get x = 8. Therefore, x is equal to 8.

The price of the motorcycle can be calculated by subtracting the amount of money received after 9 months (12 million) from the total salary received in a year (20 million). Therefore, the price of the motorcycle is 20 million - 12 million = 8 million. However, none of the given options match this calculation. Therefore, the correct answer cannot be determined based on the information provided.

Mesin A dan mesin B bekerja selama 18 jam dan menghasilkan total 60 rim. Jika kita asumsikan mesin A menghasilkan x rim, maka mesin B akan menghasilkan 60 - x rim. Berdasarkan informasi yang diberikan, mesin A dapat memfotokopi 3 rim per jam dan mesin B dapat memfotokopi 4 rim per jam. Jadi, kita dapat membuat persamaan sebagai berikut: 3x + 4(60 - x) = 60. Dengan menyelesaikan persamaan tersebut, kita dapatkan x = 36. Oleh karena itu, mesin A sedikitnya menghasilkan 36 rim.

The total price of the fruits bought by Ani, Nia, and Ina can be calculated by adding up the prices of each fruit individually. From the given information, we know that Ani bought 2 kg of apples for a certain price, Nia bought 3 kg of apples for a different price, and Ina bought 1 kg of apples for yet another price. By finding the average price per kg of apples, we can calculate the total price of 1 kg of apples. We can do the same for grapes and oranges. Finally, we add up the prices of 1 kg of each fruit to find the total price of 1 kg of apples, 1 kg of grapes, and 4 kg of oranges, which is Rp 51.000,00.
