Question 1

A store sells notebooks for $2.75 each. If Maria buys 4 notebooks and pays with a $20 bill, how much change does she receive?

Accepted Answer

$9.00

Answer

4 × $2.75 = $11.00, and $20.00 − $11.00 = $9.00 change.

Question 2

What is the slope of the line that passes through the points (2, 5) and (6, 13)?

Accepted Answer

2

Answer

Slope = (13 − 5) / (6 − 2) = 8 / 4 = 2.

Question 3

Which of the following is equivalent to 3(x + 4) − 2x?

Accepted Answer

x + 12

Answer

3(x + 4) − 2x = 3x + 12 − 2x = x + 12.

Question 4

A triangle has angles measuring 45° and 75°. What is the measure of the third angle?

Accepted Answer

60°

Answer

The angles of a triangle sum to 180°, so 180° − 45° − 75° = 60°.

Question 5

Simplify: (4x²)(3x³)

Accepted Answer

12x⁵

Answer

Multiply coefficients (4 × 3 = 12) and add exponents (2 + 3 = 5) to get 12x⁵.
