#### Work Step by Step

melting point: -38.87 degrees Celsius boiling point: 356.58 degrees Celsius $-38.87 > x$ or $x> 356.58$ $-38.87 > x$ $-38.87 = \frac{5}{9}*(F-32)$ $-38.87 * \frac{9}{5} = \frac{5}{9}*\frac{9}{5} * (F-32)$ $-69.966 = F - 32$ $-69.966 + 32 = F - 32 + 32$ $-37.966 = F$ $x > 356.58$ $356.58 = \frac{5}{9}*(F-32)$ $356.58*\frac{9}{5} = \frac{9}{5} * \frac{5}{9} * (F-32)$ $641.844 = F-32$ $641.844 + 32 = F-32 + 32$ $673.844 = F$ $-37.97 > x$ or $x > 673.844$
