1. Em uma das situações estudadas aprendemos que as escalas Celsius Fahrenheit, utilizadas para expressa medidas de temperatura, não sãc proporcionais. A relação matemática entre elas é dada pela expressão: \( \begin{array}{l}\mathrm{F}=1,8 \cdot \mathrm{C}+32 \text {, em que } \mathrm{F} \text { é dado } \\ \mathrm{em}{ }^{\circ} \mathrm{Fe} \mathrm{C} \text { é dado em }{ }^{\circ} \mathrm{C} .\end{array} \) \( \begin{array}{ll}\text { Com isso, determine: } \\ 68^{\circ} \mathrm{F} \text { em }{ }^{\circ} \mathrm{C} & \text { b) } 25^{\circ} \mathrm{C} \mathrm{em}^{\circ} \mathrm{F} .\end{array} \)
