### Grade 7 Math Sample Question 20

Simplify this expression.

4(8x + 3) + 3(2x + 6)

A) 36x + 6

B) 38x + 30 (Correct Answer)

C) 44x + 36x

D) 80x

Explanation:
Using the Distributive Property:

4(8x + 3) = 4(8x) + 4(3) = 32x + 12

3(2x + 6) = 3(2x) + 3(6) = 6x + 18

Combining the terms: 32x + 12 + 6x + 18 = 38x + 30

### Grade 7 Math Sample Question 7

Jasmin takes three walks a day. If her walks last 30 minutes, 47
minutes, and 1 hour, respectively, and she walks a total of 4 miles
a day, which of the following reflects the approximate pace she walks?

A) two and a quarter miles per hour

B) two and a half miles per hour

C) one half mile per hour (Correct Answer)

D) one quarter mile per hour

Explanation:
First, determine the total number of minutes Jasmine walks: 30 minutes + 47 minutes + 1 hour = 2 hours, 17 minutes.
This is approximately 2 and a quarter hour or 2.25 hours.

Next, since Jasmin walked a total of 4 miles, divide the distance travelled by time. 4 miles/(9/4) hours.
The result is approximately equal to one and half mile per hour.
