-2/5 x - 9 < 9/10

OpenStudy (anonymous):

\[\frac{ -2 }{ 5x } - 9 < \frac{ 9 }{ 10 }\] like that?

OpenStudy (anonymous):

x>-99/4

OpenStudy (anonymous):

thats the answer

OpenStudy (anonymous):

still won't follow the rules...?

OpenStudy (anonymous):

OpenStudy (anonymous):

well it states for you to not just post answers, but instead explain the process, and your answer is wrong -.-

OpenStudy (anonymous):

\[-\frac{ 2 }{ 5}x-9<\frac{ 9 }{ 10} \]= \[-\frac{ 2 }{ 5}x< \frac{ 9 }{ 10 }+\frac{ 9 }{ 1 }\]= \[-\frac{ 2 }{ 5}x< \frac{ 9 }{ 10 }+\frac{ 90 }{ 10 }\]= \[-\frac{ 2 }{ 5}x<\frac{ 99 }{ 10 }\]= \[-4x<99\]= \[x>-\frac{ 99 }{ 4}\]

OpenStudy (anonymous):

\[\frac{ -2 }{ 5 }x < \frac{ 99 }{ 10 }\] multiply each side by -5\[2x > 99/2\] then divide each side by 2 \[\frac{ 99 }{ 2 } * \frac{ 2 }{ 1 }\] so x > 99

-99 rather lol
