1) yes--common difference is 3.
You would get that X equals 3w over 7 + y over 7<span />
9 days
because legit 60 - 42 = 18
18 divide 2 = 9 days
Or you could’ve just done 42 + 2 +2+2 until you get to 60 and you would do it 9 times. Meaning 9 days

18 k = 504
k = 504/18
k = 28
30,000 - 19,500 = 10,500 gallons left to fill the pool. So I am assuming the answer would be w = 10,500 gallons... unless there was an equation missing in the question
