–14 < 7t < 21 We'll solve for t first, so forget the 21 for now. -14 < 7t -14 / 7 < 7t / 7 -2 < t

OpenStudy (anonymous):

okay so ...

OpenStudy (anonymous):

its c? @jcpd910

OpenStudy (anonymous):

–14 < 7t < 21 Replace t with -2.

OpenStudy (anonymous):

Is the first sign a < with a line under it?

OpenStudy (anonymous):

the ones that have equal sings next to them yes that's what they are so its either c or d right?

OpenStudy (anonymous):

It's c, like you said. :)

OpenStudy (anonymous):

Wait, misread, one sec

OpenStudy (anonymous):

D

OpenStudy (anonymous):
