Step-by-step explanation:
 
        
             
        
        
        
the first solution is 20% acid, and say we'll be using "x" liters, so how many liters of just acid are in it?  well 20% of "x" or namely 0.2x.  Likewise for the 60% acid solution, if we had "y" liters of it, the amount of only acid in it is 0.6y.


 
        
             
        
        
        
So given the formula 4 is going to be your first term 6 is the number you are multiplying/dividing! So 4x6 24 or -24
        
             
        
        
        
Answer/Step-by-step explanation:
84 = L x w
84 = 84 x 1
84 = 42 x 2
84 = 28 x 3
84 = 21 x 4
84 = 14 x 6
84 = 12 x 7
