In american football, the playing field is 53.33 yards (yd) wide by 120 yards (yd) long. for a special game, the field staff want to paint the playing field orange. of course, they will use biodegradable paint available for purchase in 25-gallon (gal) containers. if the paint is applied in a thickness of 1.2 millimeters (mm) in a uniform layer, how many containers of paint will they need to purchase?

68 containers of paint.

Step-by-step explanation:

First, we need to make the conversion from milimeters to yards. Knowing that:

We get:

Knowing that the playing field is 53.33 yards wide by 120 yards long, and the paint will be applied in a thickness of 1.2 millimeters () , we can find the volume:

Now we must make the conversion from cubic yards to gallons. Since , we get:

To find the number of containers of paint they will need to purchase, we must divide by :

step-by-step explanation:

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
