Answer:
so his total pay for Saturday would be $104.50
Step-by-step explanation:
He works 5 hours at $11 per hour which gets a total of 55$
He also works 3 hours of overtime where he gets payed 1.5x pay

49.5 + 55 = $104.50
Answer:
x=-3,x=9
Step-by-step explanation:
x^2-6x-20-7=0
x^2-6x-27=0
x^2-(9-3)x-27=0
x^2-9x+3x-27=0
x(x-9)+3(x-9)=0
(x+3)(x-9)=0
x=-3,x=9
