1) billy walks 15 miles every day to soccer practice, and catches a ride home from his grandma. billy had 5 practices last week. how many yards did billy walk last week to practice. 1760 yards 2) marks age is, t, is 3 times his age 10 years ago. write an equation to represent the statement

1 )  Billy walks 15 miles every day to soccer practice and he had 5 practices last week.

We know that,  1 mile = 1760 yards

So, 15 miles = (15× 1760) yards = 26400 yards

Thus the total distance walked in 5 practices will be:

2) Mark's current age is years

So, his age was in 10 years ago

Given that, his current age is 3 times his age 10 years ago.

So, the equation to represent this situation will be :
