Al is employed on an assembly line. He receives 35 cents for each part that he works on. If he works on more than 150 parts, his employer will pay him 40 cents for each part over 150. Yesterday, Al worked on 1,000 parts. How much did he earn?

392.50

Step-by-step explanation:

1,000-150=850

850 x .40 = 340

150 x .35 = 52.5

340 + 52.5 = 392.50

step-by-step explanation:

square root means have of a number so have of 3 is 1.5 then multiply it by 8 and you get your answer!

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
