On the second part of her trip, Tamiko drove 21 miles less than two times as far as the first part. Let f represent the number of miles driven on the first part of her trip.Then write an algebraic expression that represents the number of miles driven on the other part.

Question

(what i got from it was 2f-21 but im pretty sure that's wrong)

Answer 1

2f-21 looks good to me.

2f is two times
2f-21 is 21 less than that.

good work.

Answer 2

On the second part of her trip, Tamiko drove 29 miles less than six times as far as the first part. Let f represent the number of miles driven on the first part of her trip.Then write an algebraic expression that represents the number of miles driven on the other part

Answer 3

On the second part of her trip, Tamiko drove 29 miles less than eight times as far as the first part. Let f represent the number of miles driven on the first part of her trip. Then write an algebraic expression that represents the number of miles driven on the other part.
