We need to convert 0 and -25 °F to °C using the given equation, which is,
[tex]F=\frac{9}{5}C+32[/tex]
1st, when C = 0°, then F ?
[tex]\begin{gathered} F=\frac{9}{5}\cdot0+32 \\ F=32 \end{gathered}[/tex]
2nd, when C = -25°, then F ?
[tex]\begin{gathered} F=\frac{9}{5}\cdot(-25)+32 \\ F=-\frac{225}{5}+32 \\ F=-45+32 \\ F=-13 \end{gathered}[/tex]
