A rectangular field measures 72 meters by 81 meters. What will it cost to cover the field with pallets of grass each covering 90-square yards and costing $239 per pallet? (Hint: 1 yd 20.9 m)
It will cost $ to cover the field.
(Round to the nearest dollar as needed.).

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

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
