Answer:
6x + 7
Step-by-step explanation:
Given parameters:
Time Anna and Tamara leaves tonight = 10x - 2
Time Anna and Tamara leaves in the morning = 4x - 9
Unknown:
An algebraic expression that represents the difference in time between leaving at night and leaving in the morning = ?
Solution:
The algebraic expression is given as:
= (10x - 2) - (4x - 9)
= 10x -2 -4x + 9
= 10x -4x -2 + 9
= 6x + 7
The algebraic expression for the time difference is 6x + 7
