Question

1. let g represent the total number of hours greg will travel on his trip across the country to attend his cousin’s wedding. the first day he travels 8 hours. the second day he travels 9 hours. the third day he had mechanical problems and only drove for 4 hours. write an algebraic expression to represent how much time he has left to drive.

Explanation:

Step1: Identify total and used time

Total travel hours: \( g \).
Hours used: \( 8 + 9 + 4 \).

Step2: Calculate used time sum

\( 8 + 9 + 4 = 21 \).

Step3: Formulate remaining time

Remaining time = Total - Used = \( g - 21 \).

Answer:

\( g - 21 \)
