Answer:
80%
Step-by-step explanation:
So you basically, just make it a ratio. Since a percentage is out of 100, just make the 5 into 100. To get 5 to 100, you times 20. Then you do the same thing to the 4 which you get 80.
Length(l)= 2w
width(w)= w
Perimeter(P)= 2w+2l= 72 (simplify expression: divide each side by 2 )
P= w+l= 36 (plug in "2w" for "l")
P= w+(2w)= 36
P= 3w= 36 (divide each side by 3 to find the width)
w= 12 units
find length:
l=2w
l= 2(12)
l= 24 units
Answer:
The length of this rectangle is 24 units and the width is 12 units.
Answer:
Step-by-step explanation:
8 multiplied by .75 = 6 which is 25 percent off.
This is just simplification. If you havent done algebra before it may be difficult but you probably have. Ok we need to get x on its on so that we know what x is. So to make X on its own, we need to get rid of -7. So we plus 7 on both sides.
So we get:
x > 17
