Define x :
------------------------------------
Let the width be x.
Width = x
Length = 2x
------------------------------------
Find x :
------------------------------------
2( x + 2x) = 180
2(3x) = 180
6x = 180
x = 30
------------------------------------
Find Length and Width:
------------------------------------
Width = x = 30 feet
Length = 2x = 2(30) = 60 feet
------------------------------------------------------------------------
Answer: The length is 60 ft and the width is 30 ft.

Step-by-step explanation:
,3^2+5^2=x^2
(3+5)^2=x^2
(8)^2=x^2
64=x^2
x=√64
X=8
Answer:
10x times 1000 y minus 4x
Answer:
(x,y)=-(1,1)
Step-by-step explanation:
-2x=8-6y (divide by -2)
=> x=-4+3y
-15x=21-6y (divide by -3 for simplicity)
=>5x=-7+2y
We know that x=-4+3y, insert this into expression "5x=-7+2y"
5(-4+3y)=-7+2y
-20+15y=-7+2y
15y-2y=20-7
13y=13
y=1
Since x=-4+3y we can find x by using y=-1
x=-4+3(1)
x=-1
0 = 5/4 - 1/4x this represents the original amount. You then solve the equation and find that x = 5 representing how many pieces she will have after cutting the ribbon.
