Step-by-step explanation:
no x's are doubled
What is the formula for the perimeter of a rectangle? It is 2L + 2W, where L is the length and W is the width. We can always replace the unknown quantity after the word "than" in these types of problems with the variable x. Our problem would then be " a rectangular garden has a length that is five less than twice x." In this case, the unknown quantity after the word "than" is the width. So, if we let x represent the width, then the length can be represented by 2x - 5. Now, we can plug into the perimeter formula. 2(2x - 5) + 2x = 50
The image below shows how to solve this equation.
The perimeter of the rectangle is then 10
Answer:
x
= 5y/8
y=8x/5
Step-by-step explanation:
-3x+7y=5x+2y
7y-2y=5y
-3x+5y=5x
5x+3x=8x
5y=8x
