Suhu mula-mula di ruang freezer adalah 21 derajat C. Setelah alat pendingin di freezer itu dihidupkan, suhunya menjadi -6 derajat C. Besar penurunan suhu di ruang tersebut adalah ...
Correct Answer
D. D. 27
Explanation
The initial temperature in the freezer is 21 degrees Celsius and it decreases to -6 degrees Celsius after the cooling device is turned on. To find the temperature drop, we subtract the final temperature from the initial temperature: 21 - (-6) = 21 + 6 = 27. Therefore, the temperature drop is 27 degrees Celsius.

Dalam suatu tes, jawaban benar diberi nilai 5, yang salah diberi nilai -1, dan untuk soal yang tidak dijawab diberi nilai 0. Jika dari 20 soal, Tasya menjawab dengan benar 14 soal dan 3 soal salah serta sisanya tidak dijawab, maka nilai yang diperoleh Tasya adalah ...
Correct Answer
B. B. 67
Explanation
Tasya answered 14 questions correctly, which means she will receive a score of 5 for each correct answer. She answered 3 questions incorrectly, which means she will receive a score of -1 for each incorrect answer. The remaining questions that she did not answer will receive a score of 0. To calculate her total score, we can multiply the number of correct answers by 5, the number of incorrect answers by -1, and add the result to the number of unanswered questions multiplied by 0. Therefore, Tasya's total score is 14 * 5 + 3 * (-1) + 3 * 0 = 70 - 3 + 0 = 67.

Bila S = {1, 2, 3, 4, 5, 6}; A = {1, 2, 3, 5}, Maka komplemen A adalah ....
Correct Answer
B. B. {4, 6}
Explanation
The complement of set A is the set of elements in the universal set S that are not in A. In this case, the universal set S is {1, 2, 3, 4, 5, 6} and set A is {1, 2, 3, 5}. Therefore, the complement of A would be the elements in S that are not in A, which are {4, 6}.

Hasil pengurangan − 7x + 14 dari − 6x + 15 adalah ...
Correct Answer
A. A. x + 1
Explanation
The given expression is (-7x + 14) - (-6x + 15). When we subtract (-6x + 15) from (-7x + 14), we can distribute the negative sign to each term inside the parentheses, which gives us -7x + 14 + 6x - 15. Simplifying this expression, we can combine like terms to get -x - 1. Therefore, the correct answer is A. x + 1.
9.
Hasil dari (− 2x + 5)(3 + 5x) adalah ...
Correct Answer
C. C. − 10 x pangkat 2 + 19x + 15
Explanation
The given expression is a multiplication of two binomials. To find the product, we can use the distributive property. Multiplying the first terms of each binomial, we get -2x * 3 = -6x. Multiplying the outer terms, we get -2x * 5x = -10x^2. Multiplying the inner terms, we get 5 * 3 = 15. Multiplying the last terms, we get 5 * 5x = 25x. Combining all these terms, we get -10x^2 + 19x + 15. Therefore, the correct answer is C. -10 x pangkat 2 + 19x + 15.

(4) g adalah bilangan ganjil
yang merupakan kalimat terbuka adalah...
Correct Answer
C. C. 1, 3, dan 4
Explanation
The correct answer is C. 1, 3, and 4. This is because statement 1, "x + 15 = 10," is an equation and not an open sentence. Statement 2, "5a + 9a = 14a," is also an equation and not an open sentence. However, statement 3, "3y - 7 = 2y + 14," is an open sentence as it contains variables and an inequality. Statement 4, "g adalah bilangan ganjil," is also an open sentence as it contains a variable and a condition (odd number). Therefore, the correct answer is C. 1, 3, and 4.

Penyelesaian dari 30 + 6x = 12 adalah ...
Correct Answer
B. B. x = -3
Explanation
The given equation is 30 + 6x = 12. To solve for x, we need to isolate the variable on one side of the equation. First, we subtract 30 from both sides to get 6x = -18. Then, we divide both sides by 6 to get x = -3. Therefore, the correct answer is B. x = -3.

Umur Haryanti lima tahun lebih tua dari umur Hadi. Enam tahun yang akan datang, jumlah umur keduanya adalah 51 tahun. Umur Haryanti sekarang adalah ...
Correct Answer
C. C. 22 tahun
Explanation
Based on the given information, Umur Haryanti is currently five years older than Hadi. In six years, the sum of their ages will be 51.

Diketahui sebuah persegi panjang dengan panjang (3x + 2) cm dan lebar (2x − 1) cm. Jika keliling persegi panjang 32 cm, maka ukuran lebarnya adalah ... cm
Correct Answer
D. D. 5
Explanation
The question states that the length of the rectangle is (3x + 2) cm and the width is (2x - 1) cm. The perimeter of a rectangle is given by the formula P = 2(l + w), where P is the perimeter, l is the length, and w is the width. Given that the perimeter is 32 cm, we can set up the equation 32 = 2((3x + 2) + (2x - 1)). Simplifying this equation gives us 32 = 10x + 2. Solving for x, we find x = 3. Substituting this value back into the width equation, we find the width is 5 cm. Therefore, the correct answer is D. 5 cm.
