The answer is 32.5%
and if you need it in decimal form, it would be,

 
        
                    
             
        
        
        
Answer:
49.5
Step-by-step explanation:
just put into you calculator 
47+(15/3)/2
 
        
             
        
        
        
I think there's supposed to be a picture here. Anyway, you can find out by finding the slope of the line on the graph and comparing it to .5 which is Henry's slope. If the graphed slope is larger than .5 then Clark hikes faster, if it is less than .5, Henry hikes faster.
Hope this helps :)
 
        
             
        
        
        
Answer:
(6,7) is a solution
Step-by-step explanation:
To determine if (6,7) is a solution, we substitute the point in and see if the inequality is true
15x+11y>12
15(6) + 11(7) >12
90+77 > 12
167>12
This is true so (6,7) is a solution
