dont bother putting anything else on here except for an answer as it is the homework help section and i have a stupid teacher who doesnt explain anything!
the mean value of these cards is 3x-2-
2x-10 ? 3x
how do you work out the missing expression?
and how do you know that there is another set of cards, one with 3x, which also have a mean value of 3x-2?
thanx!

well
ur question is a little bit unclear
i guess u should rephrase it
but i really want to help
so as i understood
the missing expression goes like this
2x-10=3x
2x-3x=10
-x=10
x=-10
so acchording to the domain of defenition
when x< -10,then 2x-10>3x
when x= -10,then 2x-10=3x
when x >-10,then 2x-10<3x
i have a feeling that this isn't exactly what u wanted
but i tried
acchording to what i understood
good luck =)

Here are a few sites for you to check out that may be able to answer your questions so that you can find the answer for yourself. I hope these help you. Maybe you should let people know what grade of math you are in so they can better assist you in explaining this question of yours.

the question doesn't make much sense, maybe you should rephrase it.
