Answer:
Divide 28 by 2
Step-by-step explanation:
When the variable of interest is multiplied by something, you undo that multiplication by dividing the equation by that something.
Here, l is multiplied by 2, so the solution is found by dividing ...
... 28 = l·2
by 2 to get ...
... 28/2 = l
That is, you divide 28 by 2 to find l.
This is the original answer or question
Which of the following statements explains how to solve for l using the formula A = lw, when A = 28 1/4 and w = 2 1/2?
A Subtract 2 1/2 from 28 1/4.
B Divide 2 1/2 by 28 1/4.
C Multiply 28 1/4 by 2 1/2.
D Divide 28 1/4 by 2 1/2.
Answer: D
