When the coefficient of a term is 1 or -1, we don't write it, we just use the + or - sign. The coefficient of the c term is -1, because of the - sign in front of it and the lack of written coefficient. Any questions?
        
             
        
        
        
Answer: |3-(-8)|
Step-by-step explanation:
Given: Paige lives 3 miles east of her school. Diego lives 8 miles west of the school. 
From the picture , the number line represents the position of the houses of the two friends such that position of Paige is 3 but position of Diego is (-8) [since east and west are opposite directions]
We know that, Distance between any two points from A to B= B-A
Since distance is a positive quantity, thus
The distance between them =  miles=11 miles
 miles=11 miles
