If 2m + n = 7 and m + 2n = 5, then (2m + n)/2 =  Choices:
A) 1
B) 7/2
C) 17/5
D) 18/5
E) 4
2*(m+2m = 5) equals 2m+4n=10   2m+4n=10   - 2m + n= 7   = 3n=3   Therefore n = 1   Plug and solve...   2m + 1 = 7   2m=6   m=3   (6+1)/2= 7/2   7/2
<result>B</result>
If 2m + n = 7 and m + 2n = 5, then (2m + n)/2 =
