Write an algebraic expression for " julie runs three miles less than twice the number n that hannah runs
a.) 2n - 3
b.) 3n - 2
c.) 2n + 3
d.) 3n + 2

It is a) 2n-3 because it says three miles less than a number so you have a -3  and you have twice the number n so 2*n which is the same as 2n, then you rearrange it and you have 2n-3.

Hope this helps :)
