Question

Which of the following best describes the algebraic expression 5(x + 2) - 3 ?

A. Five times a number plus two minus three.
B. Three less than five times a number plus two.
C. Three less than five times the quantity of a number plus two.
D. Five times the quantity of a number plus two less than three.

Answer 1

A

Explanation:

brackets first according to bodmas

Answer 2

C

Explanation:

It is not A, that implies that there is no parenthesis needed. Same goes for D.

It is not B, (5x +2)-3

"Three less than" implies that 3 will be subtracted in the end of the equation.

B and C may get mixed up: C includes the phrase "the quantity" which implies the number (x) and two are added before being multiplied by 5.
