Question

Both Crystal and Jamal believe that they have the correct way to convert Celsius into Fahrenheit.

They have worked out their equations below. Who is correct Crystal or Jamal?
Please explain your reasoning.

Crystal
C=5/9(F-32)
C+32=5/9F
9/5(C+32)=F

Jamal
C=5/9(F-32)
9/5C=F-32
9/5C+32=F

Answer 1

To determine who is correct in converting Celsius to Fahrenheit, we compare Crystal and Jamal's equations by plugging in values and solving for Fahrenheit.

Step-by-step explanation:

To convert Celsius to Fahrenheit, both Crystal and Jamal have provided equations. Crystal's equation is C = (5/9)(F - 32) and Jamal's equation is 9/5C + 32 = F. Let's go step by step to determine who is correct.

Using Crystal's equation, we plug in the known Celsius value C and solve for F.

Using Jamal's equation, we plug in the known Celsius value C and solve for F.

If both equations give us the same value of F, then both Crystal and Jamal are correct.

By comparing the results from both equations, we can determine who has the correct method.

Answer 2

Jamal

Step-by-step explanation:

The multiplication must be addressed first. Multiplying both sides by 9/5 is the correct first step. then add 32 to both sides.
