Hello,
10 is not a digit!
Let' a ,b ,c the 3 digits
Numbers are
10a+b
10a+c
10b+c
10b+a
10c+a
10c+b
sum = 22a+22b+22c=22(a+b+c)
sum /(a+b+c)=22
<span>You'll only be using positive integers for the number of bus stops, and those are the whole numbers, answer d.
Hope this helps!!!^_~!!!</span>
Well remember this:
When the signs are the same it is positive
When the signs are different make it negative
When you are subtracting a negative and positive, it is going to be like adding

You can change its formed by Completing the square.
In order to do Complete the square, you can follow these steps:
1. You can identify that:
2. Then, you can find 
. This is:
3. Now you must add 
to both sides of the Quadratic equation in order to keep the balance. Then:
4. Finally, simplifying by actoring and adding the like terms, you get:
