Two times the difference of one-third of a number and three.

B.

C.

D.

Answer 1

D

Answer 2

say the number is "x"

1/3 of that number will be (1/3)x

so the difference of that and 3 would be \(\cfrac{1}{3}x-3\)

so 2 * that would be \(\bf 2\left(\cfrac{1}{3}x-3\right)\)

the given variable is "x" so what if x = 9 ?
