  Simplify the expression above. Which of the following is correct?

A. 33

B. 44

C. 25

D. 12

Answer Explanation:

Let's simplify the expression step by step:

Step 1: Inside the square brackets, perform the operation within parentheses first:

([4(3+6?5)]=[4(3+30)] ) 

Step 2: Continue simplifying inside the square brackets:

([4(3+30)]=[4ast33])

Step 3: Calculate the value inside the square brackets:

([4ast33]=132)

Step 4: Now, deal with the denominator:

((20÷5)=4)

Step 5: Finally, divide the result from step 3 by the result from step 4:

(132/4=33)

So, the simplified expression is 33.

Therefore, the Correct Answer is A.

  • Q #2: A person weighed themselves at 120 lb. Three months later they weighed themselves at 160 lb. Which of the following is the percent of weight the person gained over 3 months? (Round to the nearest percent.)

    A. 66%

    B. 33%

    C. 35%

    D. 30%

    Answer Explanation

    We need to find the percent change in weight of a person. To find the percent change, follow the following steps:

    • Find absolute change in weight
    • Find relative change
    • Find the percent change from relative change.

     Absolute change is the difference between the final value and initial value. Our initial value is 120 lb and final value is 160 lb. Then,

    Relative change is given by

    Percent change is determined by

    To the nearest whole number, the percent change is 33%.
