A contractor charges $1,200 for 100 square feet of roofing installed. at this rate, how much money does it cost to have 1,100 square feet installed

$13,200

Step-by-step explanation:

To solve this problem, we need to cross multiply. Lets input the values (1,200, 100, 1,100) as shown below:

Next we cross multiply. We multiply 100 and x, and we multiply 1,200 and 1,100.

Now, lets put the values above back into the equation:

The last step is to divide 1,320,000 by 100.

It will cost $13,200 to have 1,100 square feet installed.

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
