Question

given this equation for converting temperature from celsius ( ) to fahrenheit ( ): f=(9/5)c + 32. what is f when c is 30? a 86 b 95 c 77 d 104

Explanation:

Step1: Substitute c value

Substitute $c = 30$ into $f=\frac{9}{5}c + 32$.
$f=\frac{9}{5}\times30+32$

Step2: Calculate multiplication

$\frac{9}{5}\times30 = 9\times6=54$.
So $f = 54+32$

Step3: Calculate addition

$f=86$

Answer:

A. 86
