Answer:
Step-by-step explanation:
1 gallon = 3.78litres
hence if the acid is $33.19/gal
3.78 litres will be sold for $33.19
while 
1 litre will be sold for $33.19/3.78
1 litre will be sold for $8.78
hence the cost per liter is $8.78
 
        
             
        
        
        
The correct answer is -b+12
        
                    
             
        
        
        
Answer:I think no, because 25+35+45=150. 150x3=450

Answer:
The system of the equations has no solution; the two lines are parallel. 
Step-by-step explanation:
The equations have the same slope. In standard form, this can be seen as the same coefficients for x and y. We will multiply the second equation by -12 to reveal this.

This means the equations are parallel and will never cross. There is no solution.
