Questions and Answers
  • 1. 

    14= n+12

    • A.

      2

    • B.

      4

    • C.

      12

    • D.

      14

    Correct Answer
    A. 2
    Explanation
    The equation 14 = n + 12 implies that n is 2. This can be found by subtracting 12 from both sides of the equation, resulting in n = 2. Therefore, the correct answer is 2.

    8n=64

    • A.

      8

    • B.

      16

    • C.

      32

    • D.

      64

    Correct Answer
    A. 8
    Explanation
    The equation 8n = 64 can be solved by dividing both sides of the equation by 8. This will give us n = 8, which means that when 8 is multiplied by 8, the result is 64. Therefore, the correct answer is 8.

    10=5r

    • A.

      2

    • B.

      3

    • C.

      4

    • D.

      5

    Correct Answer
    A. 2
    Explanation
    The equation 10 = 5r can be solved for r by dividing both sides of the equation by 5. This gives us r = 2, which means that the value of r that satisfies the equation is 2. Therefore, the correct answer is 2.

    Rate this question:

  • 4. 

    15=10-r

    • A.

      -5

    • B.

      5

    • C.

      10

    • D.

      15

    Correct Answer
    A. -5
    Explanation
    The given equation is 15=10-r. To solve for r, we need to isolate it on one side of the equation. Subtracting 10 from both sides, we get 5=r. Therefore, the value of r is 5.

    2x<-30

    • A.

      X

    • B.

      X

    • C.

      X>-15

    Correct Answer
    A. X
    Explanation
    The given answer, x > -15, is correct because the original inequality states that 2x is less than -30. Dividing both sides of the inequality by 2 gives x < -15. However, since the question asks for the answer in terms of x, we can rewrite the inequality as x > -15. This means that x is any value greater than -15, which satisfies the original inequality.

  • 6. 

    12x-5<-29

    • A.

      X

    • B.

      X>2

    • C.

      X

    Correct Answer
    C. X
  • 7. 

    6x>-18

    • A.

      X

    • B.

      X>-3

    • C.

      X>3

    Correct Answer
    B. X>-3
    Explanation
    The correct answer is x>-3 because when we divide both sides of the inequality by 6, the inequality sign remains the same. Therefore, x is greater than -3.

    Rate this question:

  • 8. 

    -7x>-56

    • A.

      X

    • B.

      X>7

    • C.

      X

    Correct Answer
    A. X
