Ответ: -5°C=23°F, -10°C=14°F
Пошаговое объяснение:
[tex]\displaystyle\\\boxed {t^0F=\frac{9}{5}t^0C+32^0 }[/tex]
[tex]\displaystyle\\t^0F=\frac{9}{5}*(-5^0)+32^0=(-\frac{9*5}{5} )^0+32^0=-9^0+32^0=23^0\ \ \ \ \Rightarrow\\\\-5^0C=23^0F\\\\\\t^0F=\frac{9}{5}*(-10^0)+32^0=(-\frac{9*10}{5} )^0+32^0=-18^0+32^0=14^0\ \ \ \ \Rightarrow\\\\\ -10^0C=14^0F[/tex]
