Answer 1

a) 400°C
C/5 = F – 32 ; 400/5 = F – 32 ; 3600 = 5F – 160 ; F = 3600 + 160/5 ; F = 3760/5 ; F= 752°F

b) 99,5°F

C/5 = F – 32 ; C/5 = 99,5 – 32/9 ; 9C = 497,5 – 160 ; C = 337,5/ 9 ; C= 37,5° C

c) 180° C

180/C = F – 32/9 ; 1620 = 5F – 160 ; F = 1620 + 160/5; F = 1780/5 ; F= 356° F

d) – 49° F

C/5 = - 49 – 32/9 ; 9C = - 245 – 160 ; C = -405/9 ; C= - 45°C
