Question 209999
write (and solve) and inequality to find three consecutive odd integers with a sum between 64 and 74.
------------------------------------
1st: 2x-1
2nd: 2x+1
3rd: 2x+3
-------------------
Inequality:
64 < 2x-1+2x+1+2x+3 < 74
64 < 6x+3 < 74
61 < 6x < 71
61/6 < x < 71/6
10 1/6 < x < 11 5/6
Then x = 11
----------------------
1st = 2*11-1 = 21
2nd = 23
3rd = 25
---
sum = 21+23+25 = 69
