Question

the temperature rises by 18 degree Fahrenheit. what is rise on the Celsius scale​

Answer 1

[(F-32) × 5]/9 = C

[(18-32) × 5]/9 = C

[(-14) × 5]/9 = C

(-70)/9 = C

7.7 = C

C = 7.7°

Answer 2

we know that

$\frac{c}{5} = \frac{f - 32}{9}$

put f= 18

then

$c = \frac{(f - 32)5}{9}$

$c = \frac{ - 70}{9}$

$c = - 7 .77degree$
