Question

The formula C = 5 (F-32) can be used to convert temperatures in
degrees Fahrenheit (°F) into degrees Celsius (°C).
a What temperature in °C is equivalent to 150°F?
b What temperature in °C is equivalent to 12°F?
C Make F the subject of the formula.
d Use your rearranged formula to find what temperature in °F is
equivalent to 160°C.​

Answer 1

Step-by-step explanation:

a) To convert degree Fahrenheit to degree Celsius the formula is 5/9( F - 32)

So, F = 150

C= 5/9 ( 150 - 32)

= 5/9 × 118

=590/9

= 65.5°C

b) F = 12

C= 5/9 (12 - 32)

=5/9 × (-20)

= -100/9

= -11.11°C

c) C = 160

C= 5/9 ( F-32)

160= 5/9 (F-32)

160× 9/5 = F -32

32×9 = F -32

288= F -32

288+32=F

320 = F

= 320°F
