Activity In this activity, you will use a variable to create expressions for various relationships. Then you will use these
expressions to form a linear equation. Finally, you will find the solution to the equation,
Theresa has two brothers, Paul and Steve, who are both the same height. Paul says he is 16 inches shorter than 13
times Theresa's height. Steve says he is 6 inches shorter than 1į times Theresa's height. If they are both right, how
tall is Theresa?
To solve a problem like this one, you can use a linear equation where the variable represents Theresa's height in
inches. Let t represent Theresa's height in inches.
Question 1
The relationships for Paul's and Steve's height with respect to Theresa's height are described above. First you will
write expressions for Paul's height and for Steve's height. Then you will relate the expressions,
