The cube of 6 is ____________.

  1. 125
  2. 225
  3. 216
  4. 238

In the equation 3x + 7y = 21, at what point is the x-axis intersected?

  1. (7, 0)
  2. (0, 7)
  3. (0, 4)
  4. (4, 0)

Answer(s): A

Explanation:

The x access is intersected at the point where the y-coordinate is 0 (y = 0). Substitute 0 for the y variable in the equation. 3x + 7y = 21 = 3x + 7(0) = 21 = 3x = 21.
Therefore, x = 7. The point’s coordinates are (7, 0).



x + y = 6 and x − y = 4. Solve for x.

  1. 3
  2. 5
  3. 7
  4. 8

Answer(s): B

Explanation:

x + y = 6, so y = 6 − x. Substitute this known value for y in the second equation.
x − y = 4
x − (6 − x) = 4 x − 6 + x = 4 2x − 6 = 4
2x = 10
x = 5



Solve for y: 4(y + 3) + 7 = 3

  1. 2
  2. −2
  3. 4
  4. −4

Answer(s): D

Explanation:

4(y + 3) + 7 = 3
4y + 12 + 7 = 3
4y + 19 = 3
4y = −16
y = −4



12 yards + 14 feet ÷ by 2 = _______________.

  1. 25 feet
  2. 12 feet
  3. 32 feet
  4. 8 feet

Answer(s): A

Explanation:

Convert 12 yards and 14 feet to feet: (12 yards × 3 feet per yard) + 14 feet = 36 feet + 14 feet = 50 feet. Divide by 2 as instructed: 50 feet ÷ 2 = 25 feet.
