Christopher wants to paint a rectangular face on the side of a house that has a length of 30 feet and a width of 24 feet. He will use one coat of paint for the side of the house. Each gallon of paint will cover 350 square feet. Each can holds one gallon and costs $30. What is the minimum cost that Christopher will spend on paint?

$61.80

Step-by-step explanation:

The face of the house has a length of 30 feet and a width of 24 feet.

We have to find find the area of that face of the house:

A = L * B

A = 30 * 24 = 720 square feet

He will use one coat of paint for the side of the house.

We need to find the number of gallons he will need.

Each gallon of paint will cover 350 square feet.

The number of gallons he will need is:

720 / 350 = 2.06 gallons

Each can holds one gallon and costs $30.

The minimum amount he will need to spend is therefore:

2.06 * 30 = $61.80

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4

step-by-step explanation:

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
