1. How many miles can I expect to drive
if I have 5 gallons of gas in my tank?

1 gallon of gas gives an average of 20 miles, so 5 should get you about 100 depending on how fast your driving and what car you're driving.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this

the correct answer to your question is a. 4^4

good luck my friend!
