    8n=64 - ProProfs

    8n=64

    • 8

    • 16

    • 32

    • 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 - ProProfs

    10=5r

    • 2

    • 3

    • 4

    • 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.

    15=10-r - ProProfs

    15=10-r

    • -5

    • 5

    • 10

    • 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.

    6x>-18 - ProProfs

    6x>-18

    • X

    • X>-3

    • X>3

    Correct Answer
    A. 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.

    2x<-30 - ProProfs

    2x<-30

    • X

    • X

    • 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.
