For the 1st one we need to solve x. x-y=2 step1: x-y+y=2+y answer: x=y+2
        
             
        
        
        
1) first find the ratio of gallons to minutes which is 150/6=25, so 25 gallons a minute.now divide 20,000 by 25=800 and that is the answer
2)so, we found the proportion 25:1 or 25 gallons a minute
3)we do the same thing we did for find, find the ratio per square feet 700/2=350, next we divide 1960 by 350. that should get you 5.6
Hope I helped! :)
        
             
        
        
        
30% of 47.50 is 14.25 so the amount payed the person payed in total would be 33.50
0.30 x 47.50 = 14.25
47.50 - 14.25 = 33.50
        
             
        
        
        
I think you’d do (5,8) - (1,3) to get (4,5)
