A faulty mercury thermometer has upper and lower fixed points 21 0 ∘ F and 3 4 ∘ F . At what temperature is its reading correct?

Let both readings be x . 176 ( x − 34 ) = 180 ( x − 32 ) . 4 x = 488. x = 12 2 ∘ F . \end{document}

A faulty mercury thermometer has upper and lower fixed points $21 0^{\circ} F$ and $3 4^{\circ} F$ . At what temperature is its reading correct?

Answer:

Solution:

Let both readings be $x$ .

$\frac{( x - 34 )}{176} = \frac{( x - 32 )}{180} . 4 x = 488. x = 12 2^{\circ} F .$
