A rectangles length is 7 inches greater than its width. If the perimeter of the rectangle is 110 inches, find its length and width. I think it's w (w+7)=110

Answers

ythat's wrong, perimiter is 2l+2w or 2(l+w) or just look below at my explanation

l=w+7

perimiter=2l+2w
perimiter=2(l+w)
subsitute
2(w+7+w)=permiter
2w+14+2w=4w+14=permiter

4w+14=110
subtract 14 from both sides
4w=96
divide both sides by 4
w=24

width=24
l=w+7
l=24+7
l=31


legnth=31
width=24
the equation for perimeter is P=2(l+w)
so, the equation is 110=2(l+w)
we know that l is 7 inches greater than w
so, l=w+7
now, substitute that for l
110=2(w+7+w)
110=2(2w+7)
110=4w+14
96=4w
w=24

How to simplify 75/100

Answers

See what number go into both 75 and 100.
25 goes into both as 3*25 for 75
and 4*25 for 100
So to simplify it we take those two numbers and make another fraction
3/4
You can simplify it by dividing both numerator and denominator by 25 what will give us 3/4 (because 75 ÷ 25 = 3 and 100 ÷ 25 = 4).

I hope it will help you :)
