2001 gallons used in 5 days, so the average for one day is 2001/5=400.2 gallons.
Answer:
2z + 5
Step-by-step explanation:
you have to combine like terms

the number with the variable next to it goes first not the constant
2z + 5
the variable is z and the constant is 5 because it doesn't have variable next to it
