Hint choose values for each
let
s = 10
t = 11
u = 8
Then v has to be greater then 10
I'll let you figure out the rest.
OpenStudy (anonymous):
it was s<v
hero (hero):
Ya, we know
OpenStudy (anonymous):
v=29
hero (hero):
Why do you make that assumption?

s+t+u=29
10+11+8=29
hero (hero):
That doesn't mean v = 29
OpenStudy (anonymous):

hero (hero):
It could be 12. You never know.
hero (hero):
I know what the answer is by the way

ahh nvrmnd. forget it. i'll figure it out on my own.
hero (hero):
Let me know what you think the answer is when you figure it out.
OpenStudy (anonymous):
why?
hero (hero):
No guessing
hero (hero):
Because if you get it right, I'll give you a medal. Plus, you should want someone to verify that your answer is correct.

hero (hero):
I'm trying to tell you the answer is not A. There's no reason not to get the answer right the first time.
OpenStudy (anonymous):

OpenStudy (anonymous):
