Answer:

see explanation

Step-by-step explanation:

Given

F = $\frac{9}{5}$ (K - 273.15) + 32

Multiply through by 5 to clear the fraction

5F = 9(K - 273.15) + 160 ( subtract 160 from both sides )

5F - 160 = 9(K - 273.15) ← distribute

5F - 160 = 9K - 2458.35 ( add 2458.35 to both sides )

5F + 2298.35 = 9K ( divide both sides by 9 )

K = $\frac{5F+2298.35}{9}$

(b)

When F = 180, then

K = $\frac{5(180)+2298.35}{9}$

= $\frac{900+2298.35}{9}$

= $\frac{3198.35}{9}$

≈ 355.37 ( to the nearest hundredth )
