Since the problem is given all the total walking distance, the first thing we are going to do is find the total distance in the map:
Now that we have the distance in the map, we can establish a ratio between the walking distance and the distance in the map:
We can conclude that each inch the map represents 0.5 miles of walking distance.

Answer:
x = -14
Step-by-step explanation:
The expression to write in this problem is:
"the sum of x and 12 equals the sum of half of x and 5"
We have:
- The sum of x and 12 is:
- The sum of half of x and 5 is:
So, the equation to write in this problem is
We solve it as follows:
1) First, we subtract from both sides, and we get
2) Then, we subtract 12 from both sides:
3) Now we multiply both sides by 2:
So, this is the solution.
