Question

a. kim has 7 more than 5 times the amount sylvia has.
b. the length of a rectangle is 3 feet less than 4 times its width.

Explanation:

Step1: Define variables

Let Sylvia's amount be \( S \), Kim's amount be \( K \).

Step2: 5 times Sylvia's amount

\( 5S \)

Step3: 7 more than 5S

\( K = 5S + 7 \)

Step1: Define variables

Let width be \( W \), length be \( L \).

Step2: 4 times width

\( 4W \)

Step3: 3 less than 4W

\( L = 4W - 3 \)

Answer:

a. \( K = 5S + 7 \)
b. \( L = 4W - 3 \)
