%289%2F5%29c-32%3E-31 Start with the given inequality.


cross%285%29%28%289%2Fcross%285%29%29c%29%2B5%28-32%29%3E5%28-31%29 Multiply EVERY term by the LCD 5 to clear any fractions.


9c-160%3E-155 Multiply and simplify.


9c%3E-155%2B160 Add 160 to both sides.


9c%3E5 Combine like terms on the right side.


c%3E%285%29%2F%289%29 Divide both sides by 9 to isolate c.

Answer:

So the solution is c%3E5%2F9 which approximates to c%3E0.556

9/5c -32>-31
I'll assume that (9/5)c, not 9/(5c).
Add 32 to both sides
(9/5)c > 1
Multiply by 5
9c>5
Divide by 9
c>(5/9)
------------
Same as an equation, unless negative numbers are multiplied.
