Answer:

Step-by-step explanation:
When x = 3, y = 13
When x = 5, y = 37
Subtract both y-values to find the change:
37 - 13 = 24
Average of the change:
 = 12

Answer:
80cm^2
Step-by-step explanation:
20*5=100
10*2=20
100-20=80
 
        
             
        
        
        
I believe it is 13/60
First, you would make them have common denominators 
4/5 (12/12) is 48/60
7/12 (5/55 is 35/60
Second, you want to find the difference
48-35=13
So from that, I would assume that the difference between the two is 13/60
