  1. What is the value of 2³ × 2²?

    Answer: 32

    Add exponents: 2^(3+2) = 2⁵ = 32.

  2. Solve the inequality: x + 5 > 12.

    Answer: x > 7

    Subtract 5 from both sides to get x > 7.

  3. What is the circumference of a circle with radius 5? (Use π ≈ 3.14)

    Answer: 31.4

    C = 2πr = 2 × 3.14 × 5 = 31.4.

  4. A shirt costs $40 and is discounted 25%. What is the sale price?

    Answer: $30

    25% of 40 is 10, so 40 - 10 = $30.

  5. What is the mean of 12, 18, 24, and 6?

    Answer: 15

    (12 + 18 + 24 + 6)/4 = 60/4 = 15.

  6. Which point lies on the line y = 2x - 1?

    Answer: (3, 5)

    For x = 3, y = 2(3) - 1 = 5, so (3, 5) works.

  7. Convert 3/5 to a percentage.

    Answer: 60%

    3/5 = 0.6 = 60%.
