Answer:
Table I fill-in: 1.404
Table II fill-in: 1.661 (instead of the 2 that's there)
Step-by-step explanation:
The functions shown in Table I and II are inverses of each other. This means that the x's for Table I are the y's in Table II. And the y's in Table I are the x's in Table II. 
So look at Table II, there is a coordinate pair 
(7, 1.404). Switch the x and y and you get (1.404,7) That's your answer to fill in on Table I.
 
        
             
        
        
        
Answer:
Write a system of equations 
Step-by-step explanation:
2x + y = 15
3x - y = 20
5x = 35
x = 7
2(7) + y =15
y = 1
 
        
             
        
        
        
Step-by-step explanation:
The total surface area is 168 square units.
 
        
             
        
        
        
I would multiply 4/7 by 5 and 3/5 by 7 to get 20/35 and 21/35. The Least Common factor is 35
