The sum of three consecutive odd integers is -87. What are the integers?
You have posted 4 problems, and showed no work whatsoever.
Did you read "Read before posting"?
Is you teacher aware that you're trying to get your homework done?
It probably would have been helpful to have mentioned that, right at the beginning. Since what you're wanting is a lesson on this kind of word problem, here's a list: Google results for "number word problems.sorry if I wasn't clear that I just wanted an explanation on a lesson that I was sick for....
OK, let's take your word for it!
Your question is:
"The sum of three consecutive odd integers is -87. What are the integers?"
An odd integer is usually represented by 2n+1.
So 3 consecutive ones can be: 2n+1, 2n+3, 2n+5
SO: 2n+1+2n+3+2n+5 = -87
That's the "equation"; solve it for n.
