Question

The linear equation that converts Fahrenheit (F) to Celsius (C) is given by the

relation





(i) If the temperature is 86°F, what is the temperature in Celsius?

(ii) If the temperature is 35°C, what is the temperature in Fahrenheit?

(iii) If the temperature is 0°C what is the temperature in Fahrenheit and if the

temperature is 0°F, what is the temperature in Celsius?

(iv) What is the numerical value of the temperature which is same in both the

scales?​

Answer 1

9/5 +32 is the correct answer buddy

Answer 2

Step-by-step explanation:

$f \: = \frac{9}{5} c \: + 32$

i) F =86°

86 = 9/5 C +32

9/5 C = 86- 32

9/5 C = 54

C = 54 ×5/9

C =6×5

C =30°

ii) C= 35°

F = 9/5 × 35 +32

F= (9×7) +32

F= 63+32

F = 95°

iii) C =0°

F = 9/5 (0)+32

F = 32°

F= 0°

0 = 9/5 C+32

9/5 C = -32

C = -32 × 5/9

C=-17.78°

iv) F=C

F = 9/5 F + 32

F-32 = 9F/5

5(F-32) = 9F

5F - 160 = 9F

9 F -5F = -160

4F = -160

F = -160/4

F = -40°

C =-40°
