Joe has 45 minutes to go to soccer practice. He spent 20 minutes eating a snack and the rest of the time doing Homework. Write an equation to express how long Joe spent doing homework

Step-by-step explanation:

Total amount of time that Joe has before going to soccer practice is 45 minutes. He spent 20 minutes eating a snack. This means that amount of time left after eating the snack is total amount of time that he has - the amount of time he spent on eating the snack. This becomes

45 - 20 = 25 minutes

He spent the rest of the time doing Homework. This means that he spent 25 minutes doing homework.

The equation to express how long Joe spent doing homework will be

Let x = amount of time spent doing home

x = total amount of time he had - amount of time he spent eating snack
