  1. Simplify 7m − 3m + 2m.

    Answer: 6m

    All terms contain the same variable unit, so combine coefficients: 7 − 3 + 2 = 6.

  2. Evaluate 4x + 1 when x = 2.5.

    Answer: 11

    Substitute 2.5: 4(2.5) + 1 = 10 + 1 = 11.

  3. Which values solve 3x ≤ 12?

    Answer: x ≤ 4

    Divide both sides by positive 3. The inequality direction stays the same: x ≤ 4.
