Answer:
5n -3
Step-by-step explanation:
Try n=1 in each expression and see which gives you a first term of 2.
2-5n = 2-5·1 = -3
2n -5 = 2·1 -5 = -3
5n -3 = 5·1 -3 = 2 . . . . . this is the expression you want
5n +2 = 5·1 +2 = 7

<em>Additional comment</em>
For a common difference of 5, <em>the coefficient of n must be 5</em>. The second answer choice fails on that count also.

Answer:
There are 112 peaches, and 56 nectarines!
Step-by-step explanation:
1) Write the question in an equation:
P+N=168
2)We know that there are twice as many peaches as Nectarines, so rewrite the variable "P" as "2N":
2N+N=168
3) Combine alike terms:
3N=168
4) Divide both sides by 3:
N=56
5) Substitute 56 as N in our equation for P (2n):
2(56)
6) Solve:
P=112
