Questions and Answers
  • 1. 

    Three times Geoff’s age plus 3 is Myrka’s age. Myrka is 48.What is Geoff’s age? 

    • A.

      15

    • B.

      17

    • C.

      135

    • D.

      153

    Correct Answer
    A. 15
    Explanation
    The given information states that three times Geoff's age plus 3 is equal to Myrka's age. Since Myrka's age is given as 48, we can set up the equation 3x + 3 = 48, where x represents Geoff's age. Solving this equation, we subtract 3 from both sides and divide by 3 to find that x = 15. Therefore, Geoff's age is 15.

    Rate this question:

  • 2. 

    In the basketball game, Rachael scored 6 points less than twice the number of points Trina scored. Trina scored 9 points. How many points did Rachael score? 

    • A.

      3 points

    • B.

      12 points

    • C.

      15 points

    • D.

      18 points

    Correct Answer
    B. 12 points
    Explanation
    Rachael scored 6 points less than twice the number of points Trina scored. Since Trina scored 9 points, twice the number of points Trina scored is 2*9=18 points. Therefore, Rachael scored 6 points less than 18 points, which is 18-6=12 points.

    Rate this question:

  • 3. 

     9 + n = –2

    • A.

      -11

    • B.

      -7

    • C.

      2

    • D.

      7

    Correct Answer
    A. -11
    Explanation
    To find the value of n, we need to isolate it on one side of the equation. We can do this by subtracting 9 from both sides of the equation. This gives us n = -2 - 9, which simplifies to n = -11. Therefore, the correct answer is -11.

    Rate this question:

  • 4. 

     14 = y – 10                                                               

    • A.

      F. –24

    • B.

      G. –4

    • C.

      H. 4

    • D.

      I. 24

    Correct Answer
    D. I. 24
    Explanation
    The equation is 14 = y - 10. To solve for y, we need to isolate it on one side of the equation. Adding 10 to both sides, we get y = 24. Therefore, the correct answer is I. 24.

    Rate this question:

  • 5. 

    5 = x + 3                                                          

    • A.

      A. –8

    • B.

      B. –2

    • C.

      C. 2

    • D.

      D. 8

    Correct Answer
    C. C. 2
    Explanation
    The equation 5 = x + 3 can be solved by subtracting 3 from both sides to isolate the variable x. This gives us x = 5 - 3, which simplifies to x = 2. Therefore, the correct answer is C. 2.

    Rate this question:

  • 6. 

     t - 26 = -21  

    • A.

      F. -47

    • B.

      G. -5

    • C.

      H. 5

    • D.

      I. 47

    Correct Answer
    C. H. 5
    Explanation
    The equation t - 26 = -21 can be solved by adding 26 to both sides of the equation. This will eliminate the -26 on the left side, leaving t alone. When we add 26 to -21, we get 5. Therefore, the value of t is 5.

    Rate this question:

  • 7. 

    84 = 7d 

    • A.

      A. 8

    • B.

      B. 12

    • C.

      C. 77

    • D.

      D. 91

    Correct Answer
    B. B. 12
    Explanation
    The equation 84 = 7d can be solved by dividing both sides of the equation by 7. This gives us d = 12. Therefore, the value of d that satisfies the equation is 12, making option B the correct answer.

    Rate this question:

  • 8. 

    6z = 12 

    • A.

      F. 2

    • B.

      G. 6

    • C.

      H. 18

    • D.

      I. 72

    Correct Answer
    A. F. 2
    Explanation
    The correct answer is F. 2. To solve the equation 6z = 12, we need to isolate the variable z. We can do this by dividing both sides of the equation by 6. This will give us z = 2, meaning that the value of z that satisfies the equation is 2.

    Correct Answer
    B. B. 4
    Explanation
    To solve the equation -8x + 3 = -29, we need to isolate the variable x. First, we subtract 3 from both sides to get -8x = -32. Then, we divide both sides by -8 to solve for x. This gives us x = 4. Therefore, the correct answer is B. 4.

    C. H. -4
    Explanation
    To solve the equation 3x + 1 = -11, we need to isolate the variable x. First, we subtract 1 from both sides of the equation to get 3x = -12. Then, we divide both sides by 3 to find x = -4. Therefore, the correct answer is H. -4.

    • C.

      H. 18

    • D.

      I. 20

    Correct Answer
    D. I. 20
    Explanation
    To solve the equation 0.3a = 6, we need to isolate the variable a. We can do this by dividing both sides of the equation by 0.3. This gives us a = 6/0.3, which simplifies to a = 20. Therefore, the correct answer is I. 20.

    Rate this question:

  • 17. 

    What is the solution of x + 6 < 5? 

    • A.

      A. x < 11

    • B.

      B. x > 11

    • C.

      C. x < -1

    • D.

      D. x > -1

    Correct Answer
    C. C. x < -1
    Explanation
    The solution to the inequality x + 6 < 5 is x < -1. To find this solution, we subtract 6 from both sides of the inequality, resulting in x < -1. This means that any value of x that is less than -1 will satisfy the inequality.
