Question

81.5 F= ___ c?

Answer 1

27.5 degree celsius

Answer 2

\[T(°\text C)=\frac59\times(T(°\text F)-32)\]
\[T(°\text F)=81.5 °\text F\]
\[T(°\text C)=\frac59\times(81.6-32)=\qquad \dots\quad (°\text C)\]

Answer 3

\[F = \frac{ 9 }{ 5 }*C + 32\]

Answer 4

\[81.5 - 32 = \frac{ 9 }{ 5 }*C\]

Answer 5

\[49.5 *\frac{ 5 }{ 9 } = C\]

\[27.5 = C\]

Answer 6

27.5 degree C
