There are 20 guests at a party. the host has 8 gallons of punch. he estimates that each guest will drink 2 cups of punch if his estimate is correct how much punch will be left over at the end of the party

5.5 gallons if the guests only drink 2 cups

Step-by-step explanation:

There are 16 cups in 1 gallon

There are 20 guests

Each guest will drink 2 cups

20*2=40

40 cups is equivalent to 2.5 gallons

You then take the original 8 gallons and subtract 2.5 from 8 and you get the answer

5.5 gallons if the guests only drink 2 cups

Step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
