    3/8 × 24 = 9 students scored above 90%.

  2. Which of the following is equivalent to 2³ × 2⁴?

    Answer: 2⁷

    When multiplying powers with the same base, add the exponents: 2³ × 2⁴ = 2^(3+4) = 2⁷.

  3. A rectangle has a length of 15 cm and a width of 8 cm. What is its perimeter?

    Answer: 46 cm

    Perimeter = 2(length + width) = 2(15 + 8) = 2(23) = 46 cm.

  4. If y = 3x − 5 and x = 4, what is the value of y?

    Answer: 7

    Substitute x = 4: y = 3(4) − 5 = 12 − 5 = 7.

  5. A store marks up items by 25%. If an item costs $48, what is the selling price?

    Answer: $60

    Markup = 25% × $48 = $12; selling price = $48 + $12 = $60.

  7. A number line shows points at −3, 0, and 4. What is the distance between −3 and 4?

    Answer: 7

    Distance = |4 − (−3)| = |4 + 3| = 7.
