Marking brainliest adrian is using a metric thermometer to check the temperature of the food he is preparing. presently, it reads 50° celsius. knowing that the celsius and fahrenheit scales are related according to the equation shown below, adrian will try to figure out the food's temperature in degrees fahrenheit. which procedure will give him the correct temperature? 5/9(f - 32) =c a: only the following: multiply both sides of the equation both 9/5 add 32 to both sides of the equation 5/9(f - 32) =c b: only the following: multiply 50 by 9 divide the answer by 5 add 32 c: both procedures will give the correct temperature.

Let's see:

9 is the denominator, if we pass it to the other side it will be as multiplication.

Now, if we pass 5, the numerador, it will go as denominator.

Now just add 32 in both sides

Ok, this is the formula to discover the temperature in fahrenheit, now let's see the procedures:

A - Multiply both sides of the equation by 9/5, ok

     Ad 32 to both sides of the equation, ok

B - Multiply 50 by 9, ok

     Divide the answer by 5, ok

     Add 32, ok

So both procedures will give the correct temperature.

A

Step-by-step explanation:

Given

50oC

Formula

5/9(F - 32) = C

5/9 * 9/5 (F - 32) = 7/5 * 50

F - 32 = 70                                      Add 32

F - 32 + 32 = 70 + 32                     Add

F = 102                                         This is the correct answer.

Multiply 50 * 9 = 450

Divide by 5  = 90

Add 32 = 122

This is not correct. Only A works.
