2 miles

Step-by-step explanation:

Sara loves to go hiking.

She hiked 3 miles on Monday 4 miles on Tuesdays and 3 miles on Thursday.

Last week Sara hiked 8 miles

This week sara hiked = Monday + Tuesday + Thursday

                                   = 3 + 4 + 3

                                  = 10 miles

     Last week hiked = 8 miles

Difference in two week hiked by Sarah = 10 - 8

                                                                    = 2 miles

So, Sarah hike 2 miles more than last week.

c. 4 and 1/2 pounds is the answer! : )

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
