The area of a rectangle is <em>L x W</em>. We have to get the value of x first so that we can find the area of the rectangle.
To get the value of x
given:
<span>a. 12 & X
b. X-2 & 16 </span>
solution:
12x (x) = (8-2 ) 16
12x = 16x-32
32 = 16x-- 12x
<u>32 </u> = <u>4x</u>
4 4
8 = x
Checking:
a. 12 & X b. X-2 & 16
Area of a rectangle = L x W Area of a rectangle = L x W
=12 x 8 = (8-2) 16
Area of a rectangle = 96 = 6 (16)
Area of a rectangle = 96
Answer:
125 pages
Step-by-step explanation:
Since 80 is 64% of unknown x we can write the equation 80/x=64/100. Now cross multiply to get 8000=64x. Divide both sides by 64 to get 125=x.
Answer:
3x-4y=-16
Step-by-step explanation:
Shorter piece = x
Longer piece = 2x
x + 2x = 33
3x = 33
x = 11 feet
2x = 11 × 2
2x = 22 feet
So one piece will be 11 feet and the other will be 22 feet.
Hope this helps!
