If the 2

If the temperature is 86 degrees in Fahrenheit, what is the same temperature in Celsius?

Correct answer:

t₂ =  30 °C

Step-by-step explanation:

$$\begin{gathered} t_1=86^{\circ }\text{F } \\ {t}_2={\displaystyle \frac{5}{9}}\cdot (t_1-32)={\displaystyle \frac{5}{9}}\cdot (86-32)=30^{\circ }\text{C} \end{gathered}$$
