The Westside Bakery uses 640 pounds of four to make 1.000 loaves of bread. Each contains the same amount of four How many pounds of four are used in each loaf of bread? For each loaf of bread. pounds of flour are used.

1000 loaves = 440 pounds flour

therefore, 1 loave = ?

therefore, 1 loave = 440/1000 pounds

                            = 0.44 pounds

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
