Answer:
a.
C = 5/8 (F - 32)
C × 8 = 5/8 × 8 (F - 32)
8C = 5(F - 32)
[tex]\frac{8C}{5} = \frac{5(F - 32)}{5}[/tex]
[tex]\frac{8C}{5}[/tex] = F - 32
[tex]\frac{8C}{5} + 32[/tex] = F - 32 + 32
[tex]\frac{8C}{5} + 32[/tex] = F
b.
C = 22
F = [tex]\frac{8C}{5} + 32[/tex]
F = [tex]\frac{8(22)}{5} + 32[/tex]
F = [tex]\frac{176}{5} + 32[/tex]
F = 35.2 + 32
F = 67.2
