Tyler has decided that he wants to do repair work on the side to earn some extra money. He is trying to figure out how much to charge an hour. He asks four local repairmen how much they charge to get an idea.

He decides to find the average rate that they charge and round to the nearest dollar to determine his hourly rate.

What is Tyler's hourly rate?

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

40 x 50 = 2000

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1
