# Math Help - temperature

1. ## temperature

A metal stays solid at Fahrenheit temp below 1868.5
Determine (in terms of an inequality) those Celsisu temp, for which the metal stays solid. Use the formula

$F=9/5c+32$

This is what I've got so far:
1868.5 = (9/5)c + 32
multiply by 5
9342.5 = 9c + 160

1020.28

but then I get lost? Is this even right? Help please....

The calculation is correct. For reference, you can check your answers to questions of this type using Google . . . try doing a Google search for "1868.5 F = ? C" (without the quotes) and see what happens.

How would you state this as an inequality? It looks like T < 1868.5 F for the original figures.

3. Thank you. I thought I was way off base!
