Well if the flat fee is $4 and you pay $2 per mile and she spent a total of $32, the answer would have to be 14 miles
Yes. Yes triangles are congruent

![d\in R,\hspace{5}d\neq 0](https://tex.z-dn.net/?f=d%5Cin%20R%2C%5Chspace%7B5%7Dd%5Cneq%200)
Step-by-step explanation:
You can solve for any variable. From the first equation, let's solve for c :
![\frac{c+1}{d} =5\\\\c+1=5d\\\\c=5d-1](https://tex.z-dn.net/?f=%5Cfrac%7Bc%2B1%7D%7Bd%7D%20%3D5%5C%5C%5C%5Cc%2B1%3D5d%5C%5C%5C%5Cc%3D5d-1)
Now, replace the value of c into the other equation:
![\frac{30d}{2c+2} \\\\\frac{30d}{2(5d-1)+2} \\](https://tex.z-dn.net/?f=%5Cfrac%7B30d%7D%7B2c%2B2%7D%20%5C%5C%5C%5C%5Cfrac%7B30d%7D%7B2%285d-1%29%2B2%7D%20%5C%5C)
Using distributive property
![\frac{30d}{10d-2+2} =\frac{30d}{10d} =3](https://tex.z-dn.net/?f=%5Cfrac%7B30d%7D%7B10d-2%2B2%7D%20%3D%5Cfrac%7B30d%7D%7B10d%7D%20%3D3)
However, keep in mind that this is true for:
![d\in R,\hspace{5}d\neq 0](https://tex.z-dn.net/?f=d%5Cin%20R%2C%5Chspace%7B5%7Dd%5Cneq%200)
Length of the rectangle 11 cm, width 3X, find the perimeter of the rectangle.
The perimeter of a rectangle is calculated by adding its four sides that are equal two to two.
Perimeter = 2*Length + 2*width = 2*11cm +2*3Xcm = 22cm + 6*Xcm
Answer : perimeter = 22cm + 6*Xcm
Hope this helps!
