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 77°f to its equivalent temperature on the celsius scale. 77°f = °c

Explanation:

Step1: Substitute F value

Substitute $F = 77$ into the formula $C=\frac{5}{9}(F - 32)$. So we get $C=\frac{5}{9}(77 - 32)$.

Step2: Calculate the value in parentheses

First, calculate $77-32 = 45$. Then the formula becomes $C=\frac{5}{9}\times45$.

Step3: Multiply

$\frac{5}{9}\times45=\frac{5\times45}{9}=\frac{225}{9}=25$.

Answer:

$25$
