Answer:
10.4 miles
Step-by-step explanation:
Write an equation for the total cost paid as a function of the # of miles driven:
L(x) = $6.75 + ($3.20/mile)x
and set this equal to $40.03 to determine the # of miles Lupita rode:
L(x) = $6.75 + ($3.20/mile)x = $40.03
Isolate the x term by subtracting $6.75 from both sides:
 ($3.20/mile)x = $40.03 - $6.75 = $33.28
Finally, divide both sides by  ($3.20/mile):
x = $33.28 /  ($3.20/mile)
   =  10.4 miles
Lupita rode 10.4 miles in the taxi.
 
        
             
        
        
        
It’s the first one on the top left corner
 
        
                    
             
        
        
        
The solution would be: a = 3/4
        
                    
             
        
        
        
combining like terms in a polynomial is adding or subtracting together terms that have the same degree in the exponents. 
example. 3x^3 + 5x^6 + 2x^3 +7x + 9x^6
= 7x + 5x^3 + 14x^6
