Answer: B.  [tex]C=\dfrac{5}{9}(F-32)[/tex]

Step-by-step explanation:

The given formula : [tex]F=\dfrac{9}{5}C+32[/tex]

To convert this formula in terms of C , we first Subtract 32 on both sides , we get

[tex]F-32=\dfrac{9}{5}C[/tex]

Now multiply 5 on both the sides , we get

[tex]5(F-32)=9C[/tex]

Divide both sides by 9 we get

[tex]\dfrac{5}{9}(F-32)=C[/tex]

OR

[tex]C=\dfrac{5}{9}(F-32)[/tex]

Therefore , the formula gives the conversion from degrees Fahrenheit to degrees Celsius will be :-

[tex]C=\dfrac{5}{9}(F-32)[/tex]

Hence, the correct answer : B.  [tex]C=\dfrac{5}{9}(F-32)[/tex]
