Step by step
5x+2y=9
Move variable to the right side and change
It’s side.
5x=9-2y
Divide both sides of the equation by 5
X = 9/5 - 2/5y
Final solution
Answer: x = 9/5 - 2/5y
Length = x
width = 2x
perimeter = 138in
in order to find perimeter you add length and width twice, so;
2(2x + x) = 138
2(3x) = 138
6x = 138
x = 23
since x = 23;
the length is 23in and the width is 46in
Answer:
Length: 84 ft
Width: 56 ft
Step-by-step explanation:
Let's define some variables first.
Call the length l and width w.
We know that w = 2/3l. Therefore, we can express w in terms of l with this expression.
Now, let's set up an equation. The flower garden is rectangular, and 280 feet of fencing are used to enclose the garden. This represents perimeter.
Remember the formula for perimeter of a rectangle: 2l + 2w
Let's substitute 2/3l for w:
2l + 2*2/3l = P
2l + 4/3l = 280
2 4/3l = 280
10/3l = 280
l = 84
Now, we know that the length is equal to 84 feet. We can multiply 84 feet by 2/3 to find the width.
84*2/3 = 56
Length: 84 ft
Width: 56 ft
Let's plug these values into the formula and see if they give us the correct perimeter:
2l + 2w = P
2*84 + 2*56 = P
168 + 112
= 280 feet
These are the correct dimensions!

Hey There!
does not equal to six, because when you see fractions with the same numerator and denominator you divide, so 6/6 equals one. Therefore, <span>
does not equal to one.

Answer: 2 ft
Explanation:
We know a square has four equal sides and that the perimeter is the length around the shape.
8 ft / 4 = 2 ft
Therefore, the length of each side is 2 ft
