Answer:
-1.5,-1,0,0.5,1 is the answer 
 
        
             
        
        
        
3(2x+1) = 7-2(x+5)
    6x+3 = 7-2x-10
         -3             -3
         6x = 7-2x-10-3
       +2x     +2x
         8x = -6
        ----    -----
          8        8
           x = -3/4 
        
             
        
        
        
To find the unit rate, you would do 2.99 / 11.3 and get about 26 cents. So the unit rate would be 26 over 1 ( 26/1 ).
Hope I helped!

For every one ball, there 5 thirds of a racket.
We plot this function on a graph to visualize our model;
 
        
             
        
        
        
Answer:
Step-by-step explanation:
Let x be the number of hours
Rental A  charges:
Rate per hour  = $4.50
Rate for x hours = 4.50x
Equation: 15 + 4.50x
Rental B  charges:
Rate per hour  = $ 5
Rate for x hours = 5x
Equation:  12.50 + 5x
