Perimeter is 24.
Length is 4 greater than the width.
Let's use 'x' for width
we can write this as x+4 + x+4 + x + x
x+4 being the width+4 and x being the width
There are 4 sides to a rectangle so you are adding 4 values
Two length and two widths
so we can then combine the two lengths to make 2x+8
and then combine the two widths to make 2x
Then put it together. 2x+2x+8= 4x+8
4x+8=24
Subtract 8 from both sides
4x=16
divide both sides by 4
x=4
The width is 4.

Answer:
Hey there!
2x-5y=10
Add 5y on both sides to get: 2x=10+5y
Divide by 2, not 2x. This will isolate the x.
x=5+2.5y
x=2.5y+5
Hope this helps :)
Answer:
Bag: 800/100 = 8*15 = 120
Umbrella: 400/100 = 4*15 = 60
