    Sara and Kim together have  15 pencils.  Sara has 9  pencils. Mark and Kim together have 10 pencils.  How many pencils does Mark have?

    • A.

      5

    • B.

      34

    • C.

      8

    • D.

      4

    D. 4
    Explanation
    Sara and Kim have a total of 15 pencils, and Sara has 9 pencils. This means that Kim must have 15 - 9 = 6 pencils. Mark and Kim together have 10 pencils, so Mark must have 10 - 6 = 4 pencils.

    Steve has x dollars in his bank account.  He deposits $10 each week for 3 weeks.  His bank balance now is $70.  What is x? ( How much money did he have to start?)

    • A.

      $60

    • B.

      $20

    • C.

      $40

    • D.

      $50

    Correct Answer
    C. $40
    Explanation
    Since Steve deposits $10 each week for 3 weeks, the total amount he deposits is $10 * 3 = $30. If his bank balance now is $70, then the initial amount he had in his bank account is $70 - $30 = $40. Therefore, x, which represents the initial amount of money Steve had, is $40.

    Correct Answer
    C. - 87 , -5 , 125
    Explanation
    Lisa is in a submarine 87 feet below sea level, so her elevation is -87. Greg is snorkeling 5 feet under water, so his elevation is -5. Barb is hiking up a hill and is 125 feet above sea level, so her elevation is 125. Therefore, the elevations in order from least to greatest are -87, -5, 125.

  • 5. 

    Find the value of  n in the equation below. 2n  +  10   =   20         n = _____

    • A.

      10

    • B.

      5

    • C.

      8

    • D.

      20

    Correct Answer
    B. 5
    Explanation
    The equation is 2n + 10 = 20. To find the value of n, we need to isolate n on one side of the equation. We can do this by subtracting 10 from both sides of the equation. This gives us 2n = 10. To solve for n, we divide both sides of the equation by 2. This gives us n = 5. Therefore, the value of n in the equation is 5.

    Rate this question:

  • 6. 

    Find the value of  n in the equation below. 15  +  n   +   20  =    45          n = _______

    • A.

      10

    • B.

      5

    • C.

      12

    • D.

      8

    Correct Answer
    A. 10
    Explanation
    In the given equation, 15 + n + 20 = 45, we need to find the value of n. To solve for n, we can start by simplifying the equation. Combining like terms, we have 35 + n = 45. Next, we can isolate the variable by subtracting 35 from both sides of the equation, giving us n = 10. Therefore, the value of n is 10.

    Find the value of  n in the equation below. 12   x    23   x    9   x  n    x  56   =    0              n = _____

    • A.

      10

    • B.

      5

    • C.

      0

    • D.

      1

    Correct Answer
    C. 0
    Explanation
    The equation is a multiplication equation where the product of all the numbers is equal to 0. In order for the product to be 0, at least one of the numbers must be 0. Therefore, the value of n that makes the equation true is 0.

    Rate this question:

  • 8. 

    Find the value of  n in each equation below. 3n   +    5  =    14            n=   ____________

    • A.

      1

    • B.

      3

    • C.

      4

    • D.

      2

    Correct Answer
    B. 3
    Explanation
    The equation is 3n + 5 = 14. To solve for n, we need to isolate the variable on one side of the equation. Subtracting 5 from both sides, we get 3n = 9. Dividing both sides by 3, we find that n = 3.

    • D.

      0 , 1

    Correct Answer
    C. 0 , 2
    Explanation
    The pattern in the given sequence is that each number is increasing by 2. Starting from -8, the next number is -6, then -4, and so on. Therefore, the next two numbers in the pattern would be 0 and 2, as they follow the same pattern of increasing by 2.

    • C.

      40 , 30

    • D.

      40 , 25

    Correct Answer
    D. 40 , 25
    Explanation
    The pattern in the given sequence is that each number is decreasing by 15. Starting from 100, each subsequent number is obtained by subtracting 15 from the previous number. Therefore, the next two numbers in the pattern would be 40 and 25, obtained by subtracting 15 from 55 and 40 respectively.

      10th floor

    • D.

      12th floor

    Correct Answer
    C. 10th floor
    Explanation
    If Brett started on the 10th floor and went up 10 floors, he would be on the 20th floor. Then, if he went down 7 floors, he would be on the 13th floor. If he went up 4 floors from there, he would be on the 17th floor. Finally, if he went down 6 floors, he would be on the 11th floor. Therefore, Brett must have started on the 10th floor.
