They are equally spaced so all the circles share the same center point.
 
        
                    
             
        
        
        
In order to keep the constant, the same and not vary there must be an indirect or inverse relationship to always maintain the value of k. 
Thus both P and V are inversely related to each other.
        
             
        
        
        
Answer:
7
Step-by-step explanation:
10x-2=9x+5 because the angles are the same as m and n are parallel.
10x=9x+7
x=7
 
        
                    
             
        
        
        
Answer:
We have been given that the upstream speed is  and the down stream speed is .
Let the fisherman traveled a distance of x miles.
The total time of the trip is 6 hours.
Relations between speed (s), time (t) and distance (d) is  
Hence,  
Time upstream +  time downstream = 6
lcm = 10
=>  
Cross multiplying,  
x = 20 miles .. Answer.
