3(x-2)=12 Solve the equation above for x. Which of the following is the correct answer?  

A. 6

B. -2

C. -4

D. 2

Answer Explanation:

: In order to solve for the value of x, we use the order of operations as follows:

The first step is to divide both sides by 3

Add 2 to both sides to eliminate it from the left-hand side of the equation

x-2+2=4+2

x = 6

Thus, the value of x is 6.

Therefore, the Correct Answer is A.

  • Q #2: If a box of 55 syringes costs $660.00, which of the following is the cost of four syringes?

    A. $51.00

    B. $26.00

    C. $32.00

    D. $48.00

    Answer Explanation

    : the question requires we find the cost of four syringes.

    If we let x be the cost of four syringes, then we set up a proportion equation with cost as numerator and number of syringes as denominator. The proportion equation becomes

    Cross-multiply to solve for x

    Rearranging the above

    Divide both sides of the equation by 55

    Thus, the cost of 4 syringes is $48.
