Terry earns $10 per hour at big bob’s burgers. jill earns 20% less than terry and jerry earns $0.50 more per hour than jill. which expression represents how much jerry earns? (h represents hours)

It's 8.5h

Step-by-step explanation:

I just guessed it right on USATestPrep

step-by-step explanation:

20% of 120 is 24. if you subtract 24 from 120 you get 96

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
