Question

express a temprature of 60° F in degree Celsius .

Answer 1

$\boxed{\bold{Hello}}$

Given to us in 60 F ans we change it in degree Celsius .

Formulae = 5/9{T-32}

» T = 5/9 ( 60 - 32 )

» T = 15.55° C

Answer 2

$f = \frac{9}{5} c + 32 \\ 60 = \frac{9}{5} c + 32 \\ 60 - 32 = \frac{9}{5} c \\ \frac{28 \times 5}{9} = c \\ \frac{140}{9} = c \\ 15.5 = c$
