Question

A thermometer gives a reading of 26 degrees Celsius. Use the formula c =5/9(f-32). Write the inverse function and use it to find the equivalent temperature in Fahrenheit

Answer 1

Answer:

The answer to your question is F = 78.8

Step-by-step explanation:

Equation

                           $C = \frac{5}{9} (F - 32)$

Multiply both sides by 9

                           $9C = \frac{5(9)}{9} (F - 32)$

Simplify

                           $9C = 5(F - 32)$

Divide both sides by 5

                           $\frac{9}{5} C = \frac{5}{5} (F - 32)$

Simplify

                           $\frac{9}{5} C = F -32$

Add 32 in both sides

                           $\frac{9}{5} C + 32 = F - 32 + 32$

Simplify (Inverse)

                           $\frac{9}{5} C + 32 = F$

Substitute to find F

                           $\frac{9}{5} (26) + 32 = F$

Simplify

                                          F = 46.8 + 32

Result

                                          F = 78.8
