You need to get x alone. So first you bring the 13 over and it becomes negative because it switches signs when switching sides
13x=104-13
13x=91
The you have to divide by 13 since you are multiplying on the other side
X=91/13
Your final answer should be
X=7
Answer:
52.4
Step-by-step explanation:
% change = 100 x final initial/initial
750x.12= $90
90+20=110

<span>Given:
Price = 2$ per square foot</span>
Total price = $288
<span>Find:
The length of the floor in feet.</span>
Solution
Squares have sides of
equal length. The solution for the area of a square is:
<span>Area = x2</span>
where x is the side
length.
If each square foot
is $2 and the total is $288, we divide 288 by 2 to find out how many
square feet the floor has.
$288 / ($2 per square
foot) = 144 square feet
Take the square-root
of this value to get the length of the floor.
x = √144
x = 12
<span>Therefore, the length
of the floor is 12 feet.</span>
