Given that 8 - x = 4, we can solve for x by subtracting 8 from both sides of the equation, which gives us -x = -4. Dividing both sides by -1, we find that x = 4. Similarly, we can solve the equation 10 + y = 12 by subtracting 10 from both sides, resulting in y = 2. Finally, we can find x - y by subtracting 2 from 4, which gives us 2. Therefore, the correct answer is 2.

The shaded region in the Venn diagram represents the intersection of two sets: cars and trucks. This means that the shaded region shows people who drive both cars and trucks.

The perimeter of a square is the sum of all its sides. In this case, the perimeter is given as 16. Since a square has all sides equal in length, we can divide the perimeter by 4 to find the length of one side. Therefore, the length of one side of the square is 4.

The given numbers are all decimals, and we are asked to find the smallest one. To determine this, we compare the numbers and look for the one with the fewest digits to the right of the decimal point.

The correct answer shows the populations in ascending order from smallest to largest. The population of the first town is 11,361, followed by 11,642, then 11,924, and finally 12,102.

Christopher is nine times the age of his twin 4-year old sons. This means that if we multiply the age of the sons by 9, we will get Christopher's age. Since the sons are 4 years old, 4 multiplied by 9 is 36. Therefore, Christopher is 36 years old.

The box with the smallest volume is the one with dimensions 2" high X 3" wide X 4" long. This can be determined by calculating the volume of each box using the formula length x width x height. The volume of the first box is 2 x 3 x 4 = 24 cubic inches. The volume of the second box is 2 x 4 x 5 = 40 cubic inches. The volume of the third box is 3 x 4 x 5 = 60 cubic inches. The volume of the fourth box is 4 x 5 x 6 = 120 cubic inches. Therefore, the box with dimensions 2" high X 3" wide X 4" long has the smallest volume.

Since Rebecca and Ian were driving at the same speed, it can be assumed that their speed was constant. Rebecca took 20 minutes to drive 15 miles, which means she was driving at a speed of 15 miles/20 minutes or 0.75 miles per minute. Therefore, if Ian had to drive 30 miles, it would take him 30 miles / 0.75 miles per minute, which equals 40 minutes.

The school bus can hold 50 children. Since the first class has 14 children and the second class has 32 children, the total number of children is 14 + 32 = 46, which is less than the capacity of the bus. Therefore, these two classes can use the school bus for their field trip.

The correct answer is a reflection. A reflection is a transformation that flips a shape over a line, creating a mirror image. In Figure 5, the shape has been reflected across a line, resulting in a mirror image of the original shape.

The given answer, "or 8/20," does not equal 1/4 because when simplified, it becomes 2/5.

Each student had to give a three-minute report, and there are 24 students in the class. Therefore, the total time for all the presentations would be 3 minutes multiplied by 24 students, which equals 72 minutes. Since there are 60 minutes in an hour, the total presentation time would be 1 hour and 12 minutes.

During a 24-hour day, Shannon's cat sleeps for 5/6 of the time. To find out how many hours the cat sleeps, we can multiply 24 (total hours in a day) by 5/6. This calculation gives us 20 hours, which means the cat sleeps for 20 hours in a day.

The correct answer is 0.65 because it is the decimal representation of the fraction 65/100.

To find the area of a rectangle, we multiply its length by its width. In this case, the length of Mrs. Campton's classroom is 15 feet and the width is 22 feet. Multiplying these values together gives us an area of 330 square feet.

The O'Malley's pool is rectangular and measures 16' long and 8' wide. The question asks for the measurements of the neighbor's pool, which needs to be congruent to the O'Malley's pool. Congruent means that the two pools will have the same shape and size. Therefore, the neighbor's pool will also be rectangular and have the same length as the O'Malley's pool, which is 16', and the same width as the O'Malley's pool, which is 8'. So, the neighbor's pool will have measurements of 8' x 16'.

The given expression 8 X 2 X 6 X 2 can be simplified by performing the multiplication operations from left to right. Multiplying 8 and 2 gives 16, and then multiplying 16 and 6 gives 96. Finally, multiplying 96 and 2 gives the product of 192. Therefore, the correct answer is not available.

Andrew beat the record for the 100-yard dash by a tenth of a second. This means that Andrew's time must be one-tenth of a second faster than the previous record. Therefore, Andrew's time is 13.71 seconds minus 0.10 seconds, which equals 13.61 seconds.

Based on the information provided, the drive from point A to point B in Figure 4 is approximately 16 miles.

The arrow in Figure 2 is pointing to the number 3 3/8.

If Jennifer and Jose each swam five laps in 15 minutes, this means that they swim at a rate of one lap every three minutes. To find out how long they would need to swim 35 laps, we can multiply the rate by 35. One lap every three minutes multiplied by 35 laps equals 105 minutes. Therefore, the correct answer is 105 minutes.

The pattern in the series is that each number is obtained by multiplying the previous number by 2 and then subtracting 1. Starting with 1, we have 1*2-1=1, 1*2-1=3, 3*2-1=7, and so on. Therefore, the next number in the series would be 63*2-1=127.

The given answer, 10/15, is equal to two-thirds because when simplified, both fractions reduce to the same value. By dividing the numerator and denominator of 10/15 by their greatest common divisor, which is 5, we get 2/3. Therefore, the two fractions are equivalent.

The shaded section of the circle represents 850 types of flowers. Since the circle represents the total number of flowers, the unshaded section would represent the remaining types of flowers that are not included in the shaded section. Therefore, the unshaded section could represent 900 flowers.

Out of the twenty students, eight brought dogs, four brought birds, and two brought cats. This means that a total of 8 + 4 + 2 = 14 students brought either dogs, birds, or cats. Therefore, the remaining students, which is 20 - 14 = 6 students, brought other animals. To find the fraction, we divide the number of students who brought other animals (6) by the total number of students (20), resulting in 6/20. Simplifying this fraction gives us 3/10, which is the correct answer.

Since there is an equal number of vegetables, fruits, and breads in the grocery cart, the total number of items must be divisible by 3. Among the given options, only 42 is divisible by 3. Therefore, 42 is the possible number of items that could be in the cart.

To find the number of words Libby types per second, we need to convert her typing speed from words per minute to words per second. There are 60 seconds in a minute, so we divide 75 words by 60 to get the number of words Libby types per second. This calculation gives us 1.25, which means that Libby types 1.25 words per second.

The number 23.654 has five decimal places. The digit 5 is in the second decimal place after the decimal point, which represents hundredths.

Cecile received $10 as an allowance. She spent $1.15 on ice cream and $3.49 on a magazine. To find out how much she has left, we need to subtract the total amount she spent from her initial allowance. $10 - $1.15 - $3.49 = $5.36. Therefore, Cecile has $5.36 left.

One bag of dog food costs more than two bags of cat food because the price of the dog food is $19.85 for a 20-pound bag, while the price of the cat food is $9.24 for a 10-pound bag. Therefore, the cost per pound of the dog food is higher than the cost per pound of the cat food.

Mrs. Alvarez was out sick twice in a semester of 40 school days. To find the percentage, we divide the number of days she was out sick (2) by the total number of school days (40) and multiply by 100. This gives us (2/40) * 100 = 5 percent. Therefore, the correct answer is 5 percent.

The correct answer is 7/20. This can be determined by adding up the percentages of the ingredients in the smoothie. The yogurt, ice, and bananas make up a total of 15% + 40% + 10% = 65%. Since the remaining 35% must be the frozen strawberries, this means that the strawberries make up 35% of the smoothie. To express this as a fraction, we can write it as 35/100, which can be simplified to 7/20.

A prime factor of a number is a prime number that divides the given number without leaving a remainder. In this case, 2, 3, and 5 are prime factors of 90 because they divide 90 evenly. However, 9 is not a prime factor of 90 because it is not a prime number and it does not divide 90 evenly. Therefore, 9 is the correct answer as it is the only number among the given options that is not a prime factor of 90.

If Casey makes a 30 percent profit for every sale she makes selling cosmetics, it means that she earns an additional 30 percent of the sale price as profit. So, if she sells $300 worth of cosmetics, her profit would be 30% of $300, which is $90. Therefore, Casey will make $90.
