The length of a rectangle is 4 units shorter than half the width. If the length of the rectangle is 18 units, which equation can be used to find w, the width of the rectangle?

A or the top option

Step-by-step explanation:

I used process of elimination

B simply does not work because in order for 4 to be subtracted by another number to equal 18, that number (width) would have to be negative

C also isn't correct since if it was solved out, we would add four to both sides, making the left side equal to w/2 + 4 which isn't what we want because the length is 4 shorter, not longer

D can be dealt with in the same way, by adding w/2 on both sides, making the left side 4 + w/2, the same as the previous option.

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
