1. 6 hours

2. 72 minutes

Step-by-step explanation:

For the first one, you want to find the unit rate. to do this, you find 15%*8 which is 1.2. Then, since it's 5 days a week, you multiply that by 5. 1.2*5 is 6 and that's how you get 6 hours.

For number 2, you go back to 1.2 hours. then you multiply 1.2 by 60 because there are 60 minutes in an hour. that makes 72 so 72 minutes each day

I hope that this helped!

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
