carter drank 15.75 gallons of water in 4 weeks.he drank the same amount of water each day.about how many days altogether will it take him to drink 20 gallons?
Answers
To answer this first lets see how many gallons of water he drinks per week.
15.75 ÷ 4 = 3.9375
Now lets divide to see how much he drinks each day.
3.9375 ÷ 7 = 0.5625 20 ÷ 0.5625 = 35.5555...
So, it will take Carter about 35 and a half days to finish 20 gallons.

3x+4y=2 4x-4y=12 elimination
Answers
3x+4y=2 + 4x-4y=12 add them since 4y and -4y can cancel out 7x=14 divide each side by 7 x=2
3x+4y=2 x=2 3(2)+4y=2 substitute 6+4y=2 -6 -6 4y=-4 divide each side by 4 y=-1
3x+4y=2 4x-4y=12 Add both 7x=14 X=2 Substitute value of x in first equation Y=-1
