(Show All Work)
Equation: —————/

780 = 180 + 40x

Step-by-step explanation:

first we need to isolate the variable

780-180 = 180-180 + 40x

600 = 40x

600/40 = 40x/40

15=x

so the unit rate or rate per hour Mr. Harris earns is $15 per hour

Hope this helps!

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
