  1. A bag contains 5 red marbles, 3 blue marbles, and 2 green marbles. What is the probability of randomly picking a blue marble?

    Answer: 3/10

    P(blue) = 3 blue / 10 total = 3/10.

  2. Which expression is equivalent to 4(x + 3) − 2x?

    Answer: 2x + 12

    Distribute: 4x + 12 − 2x = 2x + 12.

  3. A triangle has angles measuring 45°, 90°, and x°. What is the value of x?

    Answer: 45

    The sum of angles in a triangle is 180°, so x = 180 − 45 − 90 = 45.

  4. Convert 0.375 to a fraction in simplest form.

    Answer: 3/8

    0.375 = 375/1000, which simplifies to 3/8 by dividing by 125.

  5. A recipe calls for 2½ cups of flour. If you want to make 3 batches, how many cups of flour do you need?

    Answer: 7½

    2½ × 3 = 5/2 × 3 = 15/2 = 7½ cups.

  6. On a coordinate plane, what quadrant contains the point (−4, 6)?

    Answer: Quadrant II

    A negative x-value and positive y-value place the point in Quadrant II.

  7. If 5n + 7 = 32, what is the value of n?

    Answer: 5

    5n = 32 − 7 = 25, so n = 25 ÷ 5 = 5.
