Answer:
12
Step-by-step explanation:
3 quarts is 6 pints 
6 pints is 12 cups
if there is 4 cups in a quart then 4x3=12
 
        
             
        
        
        
We will have the following:
*First: We determine the translation rule:
We have that the point went from (3, -4) to (0, -5), thus the translation rule would be:

Second: We apply the translation rule to the other point to determine it's image, that is:

So, the image of the second point is (5, 6).
 
        
             
        
        
        
You would do 157.5/35 to find how much gas she needs
157/35=4.5
She'll need 4.5gallons of gas
        
             
        
        
        
5, 3, 7, 9 are all non-common factors
