IF C and ...

Question

IF $C$ and $F$ denote the temperature in Celsius and Fahrenheit scale, the relation $9 C = 5 (F - 32)$ always hold. Draw the graph of this relation. From the graph, find the value of $F$ , when $C = 20$

Open in App

Solution

$9 C = 5 (F - 32)$

$\Rightarrow 9 \times 20 = 5 (F - 32)$

$\Rightarrow 36 = (F - 32)$

$\Rightarrow F = 68$
