Answer:
![\frac{2*x - 2}{2*x} - \frac{3*x + 2}{4*x} = \frac{x - 6}{4*x}](https://tex.z-dn.net/?f=%5Cfrac%7B2%2Ax%20-%202%7D%7B2%2Ax%7D%20%20-%20%5Cfrac%7B3%2Ax%20%2B%202%7D%7B4%2Ax%7D%20%3D%20%5Cfrac%7Bx%20-%206%7D%7B4%2Ax%7D)
Step-by-step explanation:
We have the expression:
![\frac{2*x - 2}{2*x} - \frac{3*x + 2}{4*x}](https://tex.z-dn.net/?f=%5Cfrac%7B2%2Ax%20-%202%7D%7B2%2Ax%7D%20%20-%20%5Cfrac%7B3%2Ax%20%2B%202%7D%7B4%2Ax%7D)
The first thing we want to do, is to have the same denominator in both equations, then we need to multiply the first term by (2/2), so the denominator becomes 4*x
We will get:
![(\frac{2}{2} )\frac{2*x - 2}{2*x} - \frac{3*x + 2}{4*x} = \frac{4*x - 4}{4*x} - \frac{3*x + 2}{4*x}](https://tex.z-dn.net/?f=%28%5Cfrac%7B2%7D%7B2%7D%20%29%5Cfrac%7B2%2Ax%20-%202%7D%7B2%2Ax%7D%20%20-%20%5Cfrac%7B3%2Ax%20%2B%202%7D%7B4%2Ax%7D%20%3D%20%5Cfrac%7B4%2Ax%20-%204%7D%7B4%2Ax%7D%20%20-%20%5Cfrac%7B3%2Ax%20%2B%202%7D%7B4%2Ax%7D)
Now we can directly add the terms to get:
![\frac{4*x - 4}{4*x} - \frac{3*x + 2}{4*x} = \frac{4*x - 4 - 3*x - 2}{4*x} = \frac{x - 6}{4*x}](https://tex.z-dn.net/?f=%5Cfrac%7B4%2Ax%20-%204%7D%7B4%2Ax%7D%20%20-%20%5Cfrac%7B3%2Ax%20%2B%202%7D%7B4%2Ax%7D%20%3D%20%5Cfrac%7B4%2Ax%20-%204%20-%203%2Ax%20-%202%7D%7B4%2Ax%7D%20%20%3D%20%5Cfrac%7Bx%20-%206%7D%7B4%2Ax%7D)
We can't simplify this anymore
I think 4. is 2 and 4. but I'm not entirely sure because I haven't done factors in a long time.
All we have to do is divide the distance of the old sidewalk by 3.14:
65 / 3.14 ≈ 20.7006
That means that, rounded to the nearest meter, the new sidewalk is:
21 meters long!
