42 < –6d A. d < –7 B. d < 36 C. d > –7 D. d < –48

pooja195 (pooja195):

divide by -6

pooja195 (pooja195):

so 42 divided by -6

OpenStudy (aaronandyson):

Divide both sides by -6

OpenStudy (aaronandyson):

so 42/-6 < -6d/-6

OpenStudy (anonymous):

-7

OpenStudy (shamim):

-6d/(-6)=?

OpenStudy (aaronandyson):

Yep

OpenStudy (aaronandyson):

-7 < d

pooja195 (pooja195):

yep thats right so whats the answer remeber here you have to flip the sign since its negative so -7<d flip the sign

OpenStudy (anonymous):

so A?

OpenStudy (texaschic101):

but remember when dividing by a negative in an inequality, it changes the inequality sign

OpenStudy (aaronandyson):

No it is C

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

thank you every one

OpenStudy (mathmate):

Remember: if -x>4 then x<-4 So if 42 < –6d, then -7 > d
