  1. If 3x - 7 = 2x + 5, what is the value of x?

    Answer: 12

    Subtract 2x from both sides to get x - 7 = 5, then add 7 to get x = 12.

  2. Which expression is equivalent to 4(2x - 3) + 8?

    Answer: 8x - 4

    Distribute 4 to get 8x - 12, then add 8 to get 8x - 4.

  3. What is the slope of the line passing through (2, 3) and (6, 11)?

    Answer: 2

    Slope = (11 - 3) / (6 - 2) = 8 / 4 = 2.

  4. Solve for y: 2y/3 = 10

    Answer: y = 15

    Multiply both sides by 3/2 to isolate y: y = 10 × (3/2) = 15.

  5. If f(x) = x² - 4x + 4, what is f(3)?

    Answer: 1

    f(3) = 9 - 12 + 4 = 1.

  6. Which inequality is satisfied by x = -3?

    Answer: 3x + 5 < -1

    3(-3) + 5 = -9 + 5 = -4, and -4 < -1 is true.

  7. What is the value of the expression 5a - 2b when a = 4 and b = 3?

    Answer: 14

    5(4) - 2(3) = 20 - 6 = 14.
