Question

EASY MATH!!! 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

Answer 1

`F=(9)/(5)C+32\\\\A.\\(9)/(5)C+32=F\ \ \ |-32\\\\(9)/(5)C=F-32\ \ \ |\cdot(5)/(9)\\\\C=(5)/(9)(F-32)`



`B.\\F=212\to C=(5)/(9)(212-32)=(5)/(9)\cdot180=100\\\\212^oF=100^oC`



`C.\\F=80\to C=(5)/(9)(80-32)=(5)/(9)\cdot48\approx26.7\\\\80^oF\approx26.7^oC`
