19) If the temperature of a liquid can be measured in Kelvin units as x° K or in Fahrenheit units as y° F, the relation between the two systems of measurement of temperature is given by the linear equation
= 59 − 2 7 3 + 3 2
(i) Find the temperature of the liquid in Fahrenheit if the temperature of the liquid is 313°K.
(ii) If the temperature is 158° F, then find the temperature in Kelvin.

Answer:
i) Temp of Liquid in Fahrenheit= 104degF
ii) Temp of Liquid in Kelvin=343degK
Step-by-step explanation:
Use the formula : ºF = 1.8 x (K - 273) + 32
i) F=1.8 x (313-273)+32=104
ii)158=1.8 x (K-273)+32
=158-32=1.8 x (K-273)
=126/1.8=K-273
=70=K-273
K=70+273=343
