## Answers and Explanations

**1. C:** When subtraction comes before division, it must be placed in parentheses. The phrase “subtract 4 from 18” means the same as “18 minus 4.”

**2. B:** All the other numbers are smaller than 21,561.72, but 21,571.72 is 10 more than 21,561.72.

**3. D:** Find the number of times 28 goes into 35; record this result (1) above the 5. Subtract 28(28 X 1) from 35 and bring down the 8. Find the number of times 28 goes into 78; record this result (2) above the 8. Subtract 56(28 X 2) from 78 and bring down the 4. Find the number of times 28 goes into 224; record this result (8) above the 4. Subtract 224(28 X 8) from 224.

**4. D:** The answer is found by dividing the number of cans by the number of dogs: 5 cans / 4 dogs. The fraction is improper, so rewrite it as a mixed number: 4 goes into 5 once (so the whole number is 1) and the remainder is 5 – 4 = 1 (so the numerator of the fraction is 1).

**5. D:** The area is found by multiplying

**6. D:** To convert from feet to inches, multiply by the factor:

**7. D:** There are 18 unit cubes on the front of the box, so the middle and the back will also have 18 unit cubes each. 18 X 3 = 54 unit cubes.

**8. A:** Point A is located at (4,2), the point four units to the right of the origin and two units above the origin.

**9. B:** A trapezoid has only one pair of parallel sides. A square, a rectangle, and a rhombus all have two pairs of parallel sides.

**10. A:** All equilateral triangles have three equal sides and three equal angles. The measure of those angles is 60°, so those angles can only be acute.
