Question

the formula c = \frac{5}{9}(f - 32) expresses the relationship between fahrenheit temperature, f, and celsius temperature, c. use the formula to convert 68°f to its equivalent temperature on the celsius scale. 68°f = □°c

Explanation:

Step1: Substitute F value

Substitute $F = 68$ into the formula $C=\frac{5}{9}(F - 32)$. So we get $C=\frac{5}{9}(68 - 32)$.

Step2: Calculate the value in parentheses

First, calculate $68-32 = 36$. Then the formula becomes $C=\frac{5}{9}\times36$.

Step3: Calculate the final result

$\frac{5}{9}\times36=5\times4 = 20$.

Answer:

$20$
