Question

what equation could be used to show sharons age
A. s=3-2b
B. b=2s-3
C. s=2b-3
D. b=3-2s
E.s=3b-2

Answer 1

To represent Sharon's age in terms of her brother's age, you can start from the statement, "Sharon is 3 years less than twice her younger brother's age."

This can be translated into the equation:

\[ s = 2b - 3 \]

Where:

• \( s \) is Sharon's age,
• \( b \) is her brother's age.

So the correct equation that shows Sharon's age is:

C. \( s = 2b - 3 \).
