Answer: 6.35444444×10^13 gallons
Step-by-step explanation:
So a dishwasher uses 444 gallons of water per load.
That means it'll use 444*215215215 = 95555555460 gallons of water for 215215215 loads
Since washing dishes by hand takes 666 as much as water in comparison to using a dishwasher, we can do 95555555460x666 to find that you need 6.36399999×10^13 gallons of water to wash 215215215 loads.
The question asks for how much more water in gallons you can save, so do 6.36399999×10^13 - 95555555460 to get 6.35444444×10^13 gallons
 
        
             
        
        
        
Answer:
Add all of the items, then multiply by 5
Step-by-step explanation:
Why by 5? Well, in order to make 
5 cookies per player one batch would be made
so, 10 cookies pp = 2 batches
15 cookies pp = 3 batches
20 cookies pp = 4 batches
 and then you would need 4 more to make 2 dozen, so you would then make another batch and have a few extra, but you would have 2 dozen per player!
hope this helps!!
 
        
             
        
        
        
To solve this system of linear equations we need a little trick called elimination steps are below 
we are given the following system of equations


if you look at the x variables in both equations you can see that we can easily eliminate them by multiplying the bottom equation by -4 as so


simplify and we get


now we can combine like terms on each side with the x's cancelling and get 

now divide off -35

great now we can go back to our original system and pick a equation and substitute y back in to find x lets use 

so now we substitute y and get




now we put x and y into one coordinate (x,y)
so now our FINAL ANSWER IS 
(-17,-1)
