Question 219502
{{{(9/5)c-32>-31}}} Start with the given inequality.



{{{cross(5)((9/cross(5))c)+5(-32)>5(-31)}}} Multiply EVERY term by the LCD {{{5}}} to clear any fractions.



{{{9c-160>-155}}} Multiply and simplify.



{{{9c>-155+160}}} Add {{{160}}} to both sides.



{{{9c>5}}} Combine like terms on the right side.



{{{c>(5)/(9)}}} Divide both sides by {{{9}}} to isolate {{{c}}}.

Answer:


So the solution is {{{c>5/9}}} which approximates to {{{c>0.556}}}
