Question

para transformarmos °C para Fahrenheit usamos a formula c/5= f-32/9. A)40°f B)80°f. C)36°f. D)68°f. E)70°f

Answer 1

A) C/5 = F - 32/9

40/5 = F - 32/9

9 = F - 32/9

81 = F - 32
F - 32 = 81
F = 81+32
F = 113

B) 80/5 = F - 32/9

16 = F - 32/9
16*9 = F - 32
144 = F - 32
F - 32 = 144
F = 144 + 32
F = 176

C) 36/5 = F - 32/9

7,2 = F - 32/9

7,2*9 = F - 32
64,8 = F - 32
F = 64,8 + 32
F = 96,8

D) 68/5 = F - 32/9
13,6 = F - 32/9
13,6*9 = F - 32
122,4 = F - 32
F = 122,4 + 32
F = 154,4
