-6w<84

OpenStudy (spyro517):

any answer choices?

OpenStudy (igreen):

To solve for 'w' we must divide -6 to both sides..can you do that? @victoriairvinxxx

OpenStudy (anonymous):

nooooooooooooo

OpenStudy (anonymous):

w>14 w<-14 w>-14 w<14

OpenStudy (igreen):

\(\sf -6w < 84\) \(\sf \dfrac{-6w}{-6} < \dfrac{84}{-6}\) \(\sf \dfrac{\cancel{-6}w}{\cancel{-6}} < \dfrac{84}{-6}\) The -6's on the left cancel out, leaving us with: \(\sf w > \dfrac{84}{-6}\) Remember, we switch the sign when dividing or multiplying by a negative number. Now all you have to do is divide 84 / -6.

OpenStudy (igreen):

Can you divide 84 / -6? @victoriairvinxxx

OpenStudy (anonymous):

yush

OpenStudy (anonymous):

@victoriairvinxxx What do you get when you divide 84 \(\div\) -6? :D

OpenStudy (anonymous):

14

OpenStudy (anonymous):

No, try again.

OpenStudy (anonymous):

84 \(\div\) negative 6.

OpenStudy (igreen):

No, it would be negative..

OpenStudy (anonymous):

-14

OpenStudy (igreen):

Yes.

OpenStudy (anonymous):

Yes!

OpenStudy (igreen):

So we get: \(w > -14\)
