Solve the following compound equality. 5m < -10 or 3m > 9

OpenStudy (kendricklamar2014):

@hlambach

OpenStudy (hlambach):

Alright lets see. Gimme a second.

OpenStudy (kendricklamar2014):

ok

OpenStudy (hlambach):

All you need to do is isolate x. So get x by itself. It is the same method you use with an equal sign.

OpenStudy (hlambach):

Sorry *isolate m

OpenStudy (kendricklamar2014):

How do u do that??

OpenStudy (hlambach):

Lets start with the first one 5m<-10 All you need to do is get 5 to the other side. SInce you are multiplying by 5, you divide by 5. 5m<-10 /5 /5 m<..... what is -10 divided by 5

OpenStudy (kendricklamar2014):

-2

OpenStudy (hlambach):

Yup. so m<-2 Now do the same thing with the other one. Thanks for becoming a fan! :)

OpenStudy (hlambach):

You can best show your thanks by giving out a medal. :)

OpenStudy (hlambach):

Thank you! :) Glad I could help!

OpenStudy (kendricklamar2014):

so what's the next step??

OpenStudy (hlambach):

Well, you just do the same exact thing with the other one and that's it.

OpenStudy (kendricklamar2014):

Is it 9/3??

OpenStudy (hlambach):

Yes.

OpenStudy (hlambach):

Let me just double check to see if you need to do anything else.

OpenStudy (kendricklamar2014):

and the answer would be 3

OpenStudy (kendricklamar2014):

what do I do with the -2 and 3??

OpenStudy (hlambach):

Well, m>3

OpenStudy (hlambach):

The final answer will be m<-2 or m>3

OpenStudy (kendricklamar2014):
