Question 1

If 5y − 3 = 2y + 9, what is the value of y?

Accepted Answer

4

Answer

Combining like terms: 3y = 12, so y = 4.

Question 2

In a class, the ratio of boys to girls is 3:5. If there are 24 boys, how many students are in the class total?

Accepted Answer

64

Answer

If 3 parts = 24, each part = 8 girls. Total parts = 8, so total students = 8 × 8 = 64.

Question 3

What are the solutions to 2x² − 8 = 0?

Accepted Answer

x = 2 or x = −2

Answer

2x² = 8 → x² = 4 → x = ±2.

Question 4

The angles of a triangle measure x°, (x + 20)°, and (x + 40)°. What is the value of x?

Accepted Answer

40

Answer

The angles sum to 180°: 3x + 60 = 180, so 3x = 120 and x = 40.

Question 5

A linear function passes through (0, −3) and has a slope of 2. Which equation represents this function?

Accepted Answer

y = 2x − 3

Answer

Using slope-intercept form with m = 2 and b = −3: y = 2x − 3.
