What are the solutions of the inequality? 12x – 3x + 11 > 4x – (17 – 9x)

OpenStudy (callisto):

12x – 3x + 11 > 4x – (17 – 9x) (12-3)x + 11 > 4x - 17 + 9x (12-3)x + 11 > (4+9)x - 17 9x + 11 > 13x - 17 Subtract 9x from both sides, what do you get?

OpenStudy (anonymous):

11>4x-17

OpenStudy (callisto):

Then, add 17 to both sides, what do you get?

OpenStudy (anonymous):

28>4x then you divide?

OpenStudy (callisto):

Divided both sides by 4

OpenStudy (anonymous):

did u get the message i sent you with the problem in it

OpenStudy (callisto):

Oh... yes... but can we finish this question first?

OpenStudy (anonymous):

its 7>x

OpenStudy (callisto):

Yes, but you need to make x on the left.

OpenStudy (anonymous):

ok thanks x<7

OpenStudy (callisto):

Yes :) Perfect!

Here's your question: p + 4 – 2(p – 10) > 0 Expand the last term on the left first p + 4 – 2(p – 10) > 0 p + 4 - 2p - 2 (-10) > 0 p + 4 - 2p + 20 > 0 Can you simplify the terms on the left first?

OpenStudy (anonymous):

p+24-2p>0

OpenStudy (callisto):

p+24-2p>0 p - 2p + 24 >0 Can you further simplify it?

OpenStudy (anonymous):

-1p+24>0

OpenStudy (callisto):

Hmmm.... -1p = -p So, you get -p + 24>0 now. Add p on both sides, what do you get?

OpenStudy (anonymous):

im not sure

OpenStudy (callisto):

-p + 24>0 p -p + 24 > 0 + p Got it?

OpenStudy (anonymous):

so its 24?

OpenStudy (callisto):

Nope :| It's inequality!

OpenStudy (anonymous):

so whats the answer

OpenStudy (callisto):

:| After simplifying it, you should get 24 > p As I've said before, p should be on the left. So, what's the answer?

OpenStudy (anonymous):

p<24

OpenStudy (callisto):

Yes :)

OpenStudy (anonymous):

okk i will proble have some more

OpenStudy (callisto):

Sorry, I'll be going soon.... Ask the question in a new thread, I'm sure some users here can help you :)
