  1. Solve for x: 3x + 7 = 22

    Answer: x = 5

    Subtracting 7 from both sides gives 3x = 15, then dividing by 3 gives x = 5.

  2. Which of the following is equivalent to 4(x - 3) + 2x?

    Answer: 6x - 12

    Distributing gives 4x - 12 + 2x, then combining like terms gives 6x - 12.

  3. If f(x) = 2x² - 3, what is f(4)?

    Answer: 29

    Substituting x = 4: f(4) = 2(16) - 3 = 32 - 3 = 29.

  4. What is the slope of the line passing through the points (2, 5) and (6, 13)?

    Answer: 2

    Slope = (13 - 5) / (6 - 2) = 8 / 4 = 2.

  5. Solve the inequality: 2x - 5 > 9

    Answer: x > 7

    Adding 5 to both sides: 2x > 14, then dividing by 2: x > 7.

  6. Which expression represents 'five less than three times a number n'?

    Answer: 3n - 5

    'Three times a number' is 3n, and 'five less than' means we subtract 5, giving 3n - 5.
