  1. Solve: |2x − 4| = 10

    Answer: x = 7 or x = −3

    Set up two equations: 2x − 4 = 10 → 2x = 14 → x = 7, and 2x − 4 = −10 → 2x = −6 → x = −3. An absolute value equation has two solutions.

  2. A scatter plot shows the number of hours studied and test scores. The data shows a strong positive correlation. What does this mean?

    Answer: As hours studied increase, test scores tend to increase

    A positive correlation means both variables tend to increase together. Correlation does not imply causation, but the pattern shows a relationship between studying and scores.

  3. Simplify: (2x³y²)²

    Answer: 4x⁶y⁴

    Apply the power rule: square each factor. 2² = 4; (x³)² = x⁶; (y²)² = y⁴. Result: 4x⁶y⁴.

  4. A recipe uses 2½ cups of flour to make 24 cookies. How many cups are needed to make 60 cookies?

    Answer: 6¼ cups

    Set up a proportion: 2.5/24 = x/60. Cross-multiply: 24x = 150. x = 150/24 = 6.25 = 6¼ cups.

  5. What is the area of a triangle with a base of 10 inches and a height of 6 inches?

    Answer: 30 in²

    Area of a triangle = (1/2) × base × height = (1/2) × 10 × 6 = 30 in².

  6. The number 72 is what percent of 240?

    Answer: 30%

    Percent = (part/whole) × 100 = (72/240) × 100 = 0.30 × 100 = 30%.
