Question

Please help thank you.

Answer 1

a)

F =
`(5)/(9)`(K - 273.15) + 32

- 32 - 32

F - 32 =
`(5)/(9)`(K - 273.15)

`(9)/(5)`(F - 32) =
`(9)/(5)`[
`(5)/(9)`(K - 273.15)]

`(9)/(5)`(F - 32) = K - 273.15

`(9)/(5)F` -
`(9(-32))/(5)` = K - 273.15

`(9)/(5)F` - 57.6 = K - 273.15

+ 273.15 + 273.15

`(9)/(5)F` - 215.55 = K

b)

`(9)/(5)(180)` - 215.55 = K

324 - 215.55 = K

108.45 = K
