  1. Solve for x: 5x − 3 = 2x + 9

    Answer: x = 4

    Subtract 2x from both sides: 3x − 3 = 9, then add 3: 3x = 12, so x = 4.

  2. A rectangle has a length of 12 cm and a width of 7 cm. What is its area?

    Answer: 84 cm²

    Area = length × width = 12 × 7 = 84 cm².

  3. Which number is irrational?

    Answer: √20

    √20 cannot be simplified to a whole number or fraction, making it irrational.

  4. If y = 2x² − 3, what is y when x = −3?

    Answer: 15

    y = 2(−3)² − 3 = 2(9) − 3 = 18 − 3 = 15.

  5. The circumference of a circle is 31.4 cm. What is its radius? (Use π ≈ 3.14)

    Answer: 5 cm

    C = 2πr → 31.4 = 2 × 3.14 × r → r = 31.4 / 6.28 = 5 cm.

  6. Which inequality represents all values of x less than or equal to 7?

    Answer: x ≤ 7

    x ≤ 7 means x is less than or equal to 7.

  7. A car travels 150 miles in 2.5 hours. What is its average speed in miles per hour?

    Answer: 60 mph

    Speed = distance / time = 150 / 2.5 = 60 mph.
