  1. What is the value of x in 3x + 7 = 22?

    Answer: 5

    Subtract 7 from both sides: 3x = 15. Divide by 3: x = 5.

  2. Which property states that a(b + c) = ab + ac?

    Answer: Distributive property

    The distributive property allows you to multiply a single term across terms inside parentheses.

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

    Answer: 30 square units

    Area = ½ × base × height = ½ × 10 × 6 = 30 square units.

  4. What is the slope of a line passing through (2,3) and (4,7)?

    Answer: 2

    Slope = (y2-y1)/(x2-x1) = (7-3)/(4-2) = 4/2 = 2.

  5. What is 15% of 200?

    Answer: 30

    15% of 200 = 0.15 × 200 = 30.

  6. What is the solution to the inequality 2x - 4 > 6?

    Answer: x > 5

    Add 4: 2x > 10. Divide by 2: x > 5.
