So \[\large \sf 42-5x > 0\] Then just solve

Nm it's D 5x 9 = 45 mb

Wait

OpenStudy (anonymous):

What? 0-0

OpenStudy (anonymous):

Sorry I am just confused XD

OpenStudy (anonymous):

If you want a positive answer, than it must be greater than 0. So I just said >0 to represent that in equation form. If you did 9, you would get 42-25=-3 which isn't a positive value.

OpenStudy (anonymous):

OH it's C

OpenStudy (anonymous):

Correct (:

OpenStudy (anonymous):

42 - 40 = 2
