  1. Solve for x: 3x − 7 = 14

    Answer: 7

    Add 7 to both sides: 3x = 21, then divide both sides by 3: x = 7.

  2. What is 35% of 120?

    Answer: 42

    Convert 35% to a decimal (0.35) and multiply: 0.35 × 120 = 42.

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

    Answer: 84 cm²

    Area of a rectangle = length × width = 12 × 7 = 84 cm².

  4. Simplify: 2³ × 2²

    Answer: 32

    When multiplying powers with the same base, add the exponents: 2³ × 2² = 2^(3+2) = 2⁵ = 32.

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

    Answer: 2

    Slope = (y₂ − y₁) / (x₂ − x₁) = (11 − 3) / (6 − 2) = 8 / 4 = 2.

  6. A jacket originally priced at $85 is on sale for 20% off. What is the sale price?

    Answer: $68

    Find the discount: 20% of $85 = 0.20 × 85 = $17. Subtract from original: $85 − $17 = $68.
