Question

Today Julia practiced her flute for 9 minutes fewer than twice the amount of time shespent yesterday. If m represents the number of minutes spent practicing yesterday,then the expression 2m-9 represents how much time she practiced today. SupposeJulia practiced for 25 minutes yesterday. How many minutes did she spend practicingthe flute today?

Answer 1

We know that

• Julie practiced her flute for 9 minutes.

,

• m, represents minutes.

The given expression is

`2m-9`

This represents the time she practiced today.

If Julia practiced for 25 minutes, then, we can solve the following

`2m-9=2(25)-9=50-9=41`

Therefore, she spent 41 minutes practicing today.
