Questions and Answers
  • 1. 

    • A.

      8/20

    • B.

      4/5

    • C.

      7/100

    • D.

      2/3

    Correct Answer
    B. 4/5
    Explanation
    The answer 4/5 is obtained by simplifying the fractions given in the question. When we simplify 8/20, we get 2/5. Similarly, when we simplify 7/100, we get 7/100. Therefore, the fractions left are 2/5 and 7/100. To add these fractions, we need to find a common denominator, which is 100. We then convert 2/5 to 40/100 by multiplying the numerator and denominator by 20. Now we can add 40/100 and 7/100, resulting in 47/100. Finally, we simplify 47/100 to 4/5.

    Rate this question:

  • 2. 

    • A.

      19/15

    • B.

      5/8

    • C.

      19/30

    • D.

      1/15

    Correct Answer
    A. 19/15
    Explanation
    The given answer is 19/15. This is the correct answer because when we divide 19 by 15, we get a fraction greater than 1. In this case, the numerator (19) is greater than the denominator (15), which means the fraction is greater than 1. Therefore, 19/15 is the correct answer.

    Rate this question:

  • 3. 

    Correct Answer
    7/12
  • 4. 

    Which of the following would you be able to combine with 7x?

    • A.

      10x

    • B.

      3y

    • C.

      11

    • D.

      12x

    Correct Answer(s)
    A. 10x
    D. 12x
    Explanation
    You would be able to combine 7x with 10x and 12x because they have the same variable (x) and can be added together. However, you cannot combine 7x with 3y or 11 because they have different variables (y and no variable) and cannot be added together.

    Rate this question:

  • 5. 

    Simplify the following expression: 4(2x - 6)

    • A.

      8x-6

    • B.

      6x -10

    • C.

      2x - 24

    • D.

      8x - 24

    Correct Answer
    D. 8x - 24
    Explanation
    The expression is simplified by distributing the 4 to both terms inside the parentheses. This results in 8x - 24.

    Rate this question:

  • 6. 

    Solve for x: x + 8 = 12

    • A.

      8

    • B.

      20

    • C.

      4

    • D.

      -4

    Correct Answer
    C. 4
    Explanation
    To solve for x in the equation x + 8 = 12, we need to isolate x on one side of the equation. To do this, we can subtract 8 from both sides of the equation. This will give us x = 4, as 12 - 8 is equal to 4. Therefore, the correct answer is 4.

    Rate this question:

  • 7. 

    Solve for x: 3x - 4 = 17

    • A.

      X= 13

    • B.

      X = 21

    • C.

      X = 47

    • D.

      X = 7

    Correct Answer
    D. X = 7
    Explanation
    To solve the equation 3x - 4 = 17, we need to isolate the variable x. First, we add 4 to both sides of the equation to get 3x = 21. Then, we divide both sides by 3 to solve for x, which gives us x = 7.

    Rate this question:

  • 8. 

    Solve for x: 4x - 3 = 2x + 5

    • A.

      X = 4

    • B.

      X = 8

    • C.

      X = 2

    • D.

      X = 6

    Correct Answer
    A. X = 4
    Explanation
    The equation 4x - 3 = 2x + 5 is solved by first subtracting 2x from both sides to isolate the x term. This gives us 2x - 3 = 5. Then, we add 3 to both sides to isolate the x term further. This gives us 2x = 8. Finally, we divide both sides by 2 to solve for x, resulting in x = 4.

    Rate this question:

  • 9. 

    Solve for x: 4x = 52

    Correct Answer
    x = 13
    13
    x=13
    x= 13
    x =13
    Explanation
    The equation 4x = 52 can be solved by dividing both sides of the equation by 4. This will give us x = 13. The answer is repeated multiple times in the given options, which is x = 13.

    Rate this question:

  • 10. 

    2x + 8 = -10

    Correct Answer
    x = -9
    -9
    x=-9
    x= -9
    x =-9
    Explanation
    The given equation is 2x + 8 = -10. To solve for x, we need to isolate x on one side of the equation. Subtracting 8 from both sides, we get 2x = -18. Dividing both sides by 2, we find x = -9. Therefore, the correct answer is x = -9.
