Easy ! the formula f=9/5c+32 is used to convert celsius to fahrenheit temperature. a. solve the formula for c b. the boiling point of water is 212 f what is c? if a house thermostat was set at 80f what is c? answer at nearest tenth. do this

F=\dfrac{9}{5}C+32A.\\\dfrac{9}{5}C+32=F\ \ \ |-32dfrac{9}{5}C=F-32\ \ \ |\cdot\dfrac{5}{9}C=\dfrac{5}{9}(F-32)

B.\\F=212\to C=\dfrac{5}{9}(212-32)=\dfrac{5}{9}\cdot180=100212^oF=100^oC

C.\\F=80\to C=\dfrac{5}{9}(80-32)=\dfrac{5}{9}\cdot48\approx26.780^oF\approx26.7^oC
