  1. What is the value of |-15 + 8|?

    Answer: 7

    |-15 + 8| = |-7| = 7, since absolute value is always non-negative.

  2. If 5x + 3 = 2x + 18, what is x?

    Answer: 5

    Subtracting 2x from both sides: 3x + 3 = 18; then 3x = 15, so x = 5.

  3. A store marks up an item by 25% from its cost of $80. What is the selling price?

    Answer: $100

    Markup = 25% × $80 = $20; selling price = $80 + $20 = $100.

  4. What is the median of the data set: 4, 7, 2, 9, 5?

    Answer: 5

    Ordered: 2, 4, 5, 7, 9; the middle value is 5.

  5. Evaluate: 2⁴ - 3²

    Answer: 7

    2⁴ = 16 and 3² = 9; 16 - 9 = 7.

  6. What is the value of x if (x/3) + 4 = 9?

    Answer: 15

    Subtracting 4 from both sides: x/3 = 5; multiplying by 3: x = 15.

  7. Two supplementary angles are in a ratio of 2:3. What is the measure of the smaller angle?

    Answer: 72°

    Supplementary angles sum to 180°; ratio 2:3 → 2 parts + 3 parts = 5 parts = 180°, so each part = 36°; smaller angle = 2 × 36° = 72°.
