Answer:  Company B charges $(15.5+0.12x) more for x miles than company A.
Step-by-step explanation:
Let x = Number of miles.
Total charge = Flat charge + (charge per mile) x  (Number of miles)
Given: 
For Company A ,
Flat charge= $45
Charge per mile =  11 cents  = 0.11   [ 1 dollar = 100 cents i.e. 1 cent = 0.01 dollar]
Total charge = 45+0.01x
For Company B,
Flat charge= $60.50
Charge per mile =  13 cents  = 0.13
Total charge = 60.50+0.13x
Difference in charge = Charge for company B -  Charge for company A
= 60.50+0.13x-(45+0.01x)
= 15.5+0.12x
Hence,  Company B charges $(15.5+0.12x) more for x miles than company A.
 
        
             
        
        
        
Answer:
y= -76
Step-by-step explanation:
y/4=-19
*4  *4
 
        
                    
             
        
        
        
This one is worded oddly, but I think it's going to be:
(2x)/19
