The field Archie will cover with grass seed is rectangular and measures 100 yards long by 60 yards wide.
B. Write an equation that describes the relationship between the number of
square yards (x) of ground to be covered and the number of scoops () of
grass seed needed. Use the equation to determine the number of scoops
of grass seed Archie needs to cover the entire field. Show or explain all
your work.

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

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
