To solve this equation, we need to isolate
on one side of the equation algebraically. I see that we have like terms, but they are on opposite sides of the equal sign. Let's add
to both sides.

To isolate x, divide both sides by 7.

Answer:
The cost of homes per square foot differs in different part of the United states. The cost of homes per square foot is gotten by using the formula:
cost of homes per square foot = Cost of apartment / area of apartment
1) Cost of apartment = $540000, area of apartment = 450 ft²
cost of homes per square foot = Cost of apartment / area of apartment = $540000/ 450 ft² = $1200 / ft²
2) cost of homes per square foot = $110/ ft², area of apartment = 2100 ft²
cost of homes per square foot = Cost of apartment / area of apartment
$110 / ft² = Cost of apartment / 2100 ft²
Cost of apartment = $110 / ft² × 2100 ft² = $231000

Answer:
CU = 117
Step-by-step explanation:
Since we have similar triangles, we can use proportions. Put the small triangle sides over the large triangle side.
WC WD
----------- = -------------
WU WV
26 20
----------- = -------------
36x-1 110
Using cross products
26*110 = 20* (36x-1)
Distribute
2860 = 720x - 20
Add 20 to each side
2860+20 = 720x-20+20
2880 = 720x
Divide by 720
2880/720 = 720x/720
4=x
We need to find CU
CU = WU - WC
Substituting in what we know
CU = 36x-1 -26
Since we know x=4
= 36*4 -1 -26
144 - 27
= 117
