Which of the following is equal to: (2x/3 - 7) + 7 The order of the mathematical operations is PEMDAS. Therefor the first step you will take is to solve the operation inside the parenthesis. (2x/3 - 7) =(2x/3 - 7)* 3/3 = 2x/3 - 21/3 = (2x - 21)/3 While adding or subtracting fractions, dont forget to check that each term have the same denominator.
<span>The correct answer is D. The number 7 is subtracted from the first term, 2x/3, but then an equal sum is added, and the two effectively cancel each other out. This means that the value of the first expression is essentially 2x/3, which is option D.</span>
r^2*h/3
