Question

Transforme na formula -10°f em °c
transforme na formula 72 °c em °f
transforme na formula 85 °c em °f

Um doente está com febre de 42°c qual é essa temperatura na escala FAHRENHEIT ?

Answer 1

42°C/5 = F - 32/9
5F - 160 =378
5F= 378 + 160
5F= 538
F= 538/5
F= 107°F

Answer 2

Converter -10 °F em °C, veja:

$\mathsf{\dfrac{\°C}{5} = \dfrac{\°F -32}{9}}\\\\\\ \mathsf{\°C}{5} = \dfrac{-10-32}{9}}\\\\\\ \mathsf{\°C}{5} = \dfrac{-42}{9}}\\\\\\ \mathsf{9\°C = -210}}\\\\\ \mathsf{ \°C = \dfrac{-210}{9}}\\\\\ \large\boxed{\boxed{\boxed{\mathsf{ \°C \approx -23,33}}}}}}}}}$

Ou seja, -10 °F equivale a aproximadamente -23,33 °C.

Converter 72 °C para °F, veja:

$\mathsf{\dfrac{\°C}{5} = \dfrac{\°F -32}{9}}\\\\\\ \mathsf{72}{5} = \dfrac{\°F -32}{9}}\\\\\ \mathsf{5\°F - 160 = 648}}\\\\\\ \mathsf{5\°F = 648 + 160}}\\\\\ \mathsf{5\°F = 808}}\\\\\ \mathsf{\°F = \dfrac{808}{5}}\\\\\ \large\boxed{\boxed{\boxed{\boxed{\mathsf{\°F = 161,6.}}}}}}}}}}}}$

Ou seja, 72 °C equivale a 161,6 °F.

Converter 85 °C em °F, veja:

$\mathsf{\dfrac{\°C}{5} = \dfrac{\°F -32}{9}}\\\\\\ \mathsf{85}{5} = \dfrac{\°F -32}{9}}\\\\\ \mathsf{5\°F - 160 = 765}}\\\\\ \mathsf{5\°F = 925}}\\\\\ \mathsf{\°F = \dfrac{925}{5}}\\\\\ \large\boxed{\boxed{\boxed{\mathsf{\°F = 185.}}}}}}}}}$

Ou seja, 85 °C equivale a 185 °F.

Converter 42 °C em °F, veja:

$\mathsf{\dfrac{\°C}{5} = \dfrac{\°F -32}{9}}\\\\\\ \mathsf{42}{5} = \dfrac{\°F -32}{9}}\\\\\ \mathsf{5\°F - 160 = 378}}\\\\\ \mathsf{5\°F = 378 + 160}}\\\\\ 5\°F = 538}}\\\\\ \mathsf{\°F = \dfrac{538}{5}}\\\\\ \large\boxed{\boxed{\boxed{\boxed{\mathsf{\°F = 107,6}}}}}}}}}}}}$

Ou seja, 42 °C equivale a 107,6 °F.

Espero que te ajude. :-).
