I need to solve these problems.

Anabel uses 10 gallons of gas to drive 220 miles on the highway. if she travels at the same rate, how many miles can she drive on 7 gallons of gas

Elena and her husband marc both drive to work. elena's car has a current mileage (total distance driven) of 15,000 and she drives 23,000 miles more each year. marc's car has a current mileage of 46,000 and he drives 9,000 miles more each year. will the mileages for the two cars ever be equal? explain.

Aline that intersects one of two parallel lines intersects the other also always sometimes never
