Question

Using the formula C=5/9(F-32); f=fahrenheit, if the celcius (C) temperature increased 35 degrees, by how many degrees would the Fahrenheit temperature be increased? A) 19 & 4/9 B) 31 degrees C) 51 Degrees D) 63 degrees E) 82 degrees

Answer 1

\[C=\frac{5}{9} *(F-32)\]
\[F=\frac{9C+160}{5}\]
celcius (C) temperature increased 35 degrees
\[C+35=\frac{5}{9} *(F_ {new} -32)\]
\[9C+315=5(F_ {new} -32)\]
\[9C+315=5F_ {new}-160\]
\[F_ {new}=\frac{9C+475}{5}\]
increase in Fahrenheit=\[F_ {new}-F=\frac{9C+475}{5}-\frac{9C+160}{5}\]
\[F_ {new}-F=\frac{315}{5}=63\]
