Hint: get rid of 13.

OpenStudy (anonymous):

ok

OpenStudy (aravindg):

try multiplying both sides of equation with 13 :)

OpenStudy (aravindg):

what do you get ?

OpenStudy (anonymous):

wait but moderator person said get rid of the 13 mind jumble

OpenStudy (anonymous):

any idea?

OpenStudy (anonymous):

To get rid of the 13, you have to do the opposite of what its doing. Here, the 13 is dividing , so the opposite of dividing is multiplying. So, multiply both sides by 13 to cancel the 13 on the left side. :o)

OpenStudy (anonymous):

ok thanks

OpenStudy (anonymous):

Do you understand how to do that? :o)

OpenStudy (anonymous):

sorta but the letter is messing with my head

OpenStudy (anonymous):

Well, you're trying to get d alone so you can find its value. So, we must do the opposite operations to undo what we did to get it to the point its at. I'll show you what it'll look like: \[\frac{ d }{ 13 } ≥ -3\] \[\frac{ d }{ 13 }(13) ≥ -3(13)\] \[d ≥ -39\] Does that make sense? :o)

OpenStudy (anonymous):

ya it does a bit more

OpenStudy (anonymous):

oh i see how you got that yay

OpenStudy (anonymous):

omagawsh thanks so much im a fan :D

OpenStudy (anonymous):

OpenStudy (anonymous):
