Answer:

6x + 7

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
