Answers

2x = 18
x = 18/2
x = 9

4(.25x + .5y = 3.75) → x + 2y = 15
(4x – 8y = 12) → x – 2y = 3

- 2y = 3 - x
- 2y = 3 - 9
- 2y = - 6
y = - 6/ - 2
y = 3

A rectangle's length is 3 more than it width, if the perimeter is 26 inches, what is the width of therectangle.

Answers

Answer:

So the width is 3.25

Step-by-step

If the perimeter of a rectangle is 300 and the length is two times the

width, what are the length and the width?

Call the width of the rectangle x. Then, if the length is three times the width, the length must be 3x.
Now, if you have a rectangle whose width is x and whose length is 3x, the perimeter must be 3x + 3x + x + x = 8x.
You are told that the perimeter is 26, so the equation is 8x = 26.
Dividing both sides by 8, one gets x = 3.25. So the width is 3.25 and the length is 6.5.

*Please don't get upset if this is incorrect, I am in 9th grade and I have severe dyslexia and dyscalculia*

Final answer:

Given the length is 3 more than the width, and the perimeter is 26 inches, by solving the equation corresponding to the perimeter of the rectangle, we find that the width of the rectangle is 5 inches.

Explanation:

The question is asking for the width of a rectangle given that its length is 3 more than its width and the perimeter is 26 inches. Let's denote the width as x. Therefore, the length is x + 3.

The formula for the perimeter of a rectangle is 2*(length + width), which in this case translates into 2*(x + (x + 3)). As given, this equals 26. Solving the equation 2*(2x + 3) = 26, we find that x = 5. Therefore, the width of the rectangle is 5 inches.
