PLEASE HELP HOW DO I TRANSLATE IT TO A PROPORTION!!

See below.

Step-by-step explanation:

A proportion is setting two ratios equal to each other.

Look at the info you are given for price in $ and area in sq ft:

$385 for 70 sq ft

That allows you to write a ratio. The ratio of dollars to square feet is

385/70    (notice it's dollars divided by sq ft)

Now you look at the part of the problem that has an unknown, and you set up the same type of ratio (dollars to sq ft) using x for the unknown.

x dollars to 200 sq ft

The ratio is

x/200     (notice that, again, it's dollars divided by sq ft)

In both cases the ratios are dollars to sq ft.

To set up a proportion, you just set the ratios equal to each other.

385/70 = x/200

Now we solve the proportion. We can cross multiply.

385/70 = x/200

70x = 385 * 200

70x = 77,000

x = 1100

They would charge $1100 to install 200 sq ft of tile.

The unit price is obtained by dividing a cost by the corresponding area in sq ft. you can use either ratio.

unit price = ($385)/(70 sq ft) = $5.5/sq ft

($1100/200 sq ft also works since it is also equal to $5.5/sq ft)

step-by-step explanation:

d

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
