Find the solution to the inequality 8x+2(x+5)>50

OpenStudy (goldphenoix):

Act as if the inequality was an equation, except with the greater than sign. So what do you think you do first with: 8x+2(x+5)

OpenStudy (anonymous):

add in parenthesids

OpenStudy (anonymous):

yeah

OpenStudy (anonymous):

good job so far

OpenStudy (anonymous):

wait me

OpenStudy (goldphenoix):

Well here's the thing. We can't add the things inside the parenthesis because it's not like term. So we have to do the distribute property. Do you know how to do the distribute property?

OpenStudy (anonymous):

no i forgot

OpenStudy (anonymous):

2x+10

OpenStudy (anonymous):

for parenthesis

OpenStudy (anonymous):

so its 8x+2x+10 now

OpenStudy (goldphenoix):

|dw:1372351945503:dw|

OpenStudy (goldphenoix):

So after doing that, our inequality should look like: 8x+2x+10>50 What do we do next? Well, can we combine like term in the left side?

OpenStudy (anonymous):

yess much better but then wats the solution of the inquALITY

OpenStudy (goldphenoix):

I can't answer it for you. I can only help you. :) So what do ew do next?

OpenStudy (goldphenoix):

So what do we do next*

OpenStudy (anonymous):

yeah hes right

OpenStudy (anonymous):

the answers 6x>40 i think

OpenStudy (anonymous):

did you get that

OpenStudy (anonymous):

x>4
