Answer 4

please, you have to use the subsequent inverse formula:
\[C=\frac{ 5 }{9 }(F-32)\]

Answer 5

please, try to substitute your fahrenheit temperatures, and get the correspondent celsius temperatures

Answer 6

for example:
\[t _{1}=\frac{ 5 }{ 9 }(49-17)\approx 10\]

Answer 7

Sorry, an error is occurred! I retry:
\[t _{1}=\frac{ 5 }{ 9 }(49-32) \approx 10\]

Answer 8

thanks

Answer 9

other temperature is:
\[t _{2}=\frac{ 5 }{ 9 }(72-42) \approx 21\]
so the difference is : 21-10=11
