Brenden runs six times a week for thirty minutes and lifts three times a week for twenty minutes. Write a mathematical expression for the number of hours Brenden works out in a week.

Step-by-step explanation:

Let the number of hours for running be x

And the number of hours for lifts be y

Let the total hours for work out be H

Given that

x= 30 min* 6= 180 min =3 hours

y= 20 min *6 =120 min=  2  hours

H= 30(6)+ 20(6)

H= 180+120

H= 3+2

H= 5 hours of work out for the  week

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
