Express the formula for converting Celsius temperatures to Fahrenheit.
Homework Equations
C= (F+40)(5/9) - 40
The Attempt at a Solution
C= (F+40)(5/9) - 40
You need to add 40 to both sides.. I don't know where you've got that 40 from inside the brackets. The next line should readC- 40= (F+40 - 40)(5/9) - 40

Changing the subject of a formula involves rearranging the equation to isolate a different variable or term. This is often done to solve for a specific variable or to simplify the equation for further calculations.
It is important for scientists to be able to change the subject of a formula because it allows for more efficient problem solving and analysis. By isolating specific variables, scientists can better understand the relationships between different components of a formula.
The steps for changing the subject of a formula include identifying the variable to be isolated, using inverse operations to move all other terms to the opposite side of the equation, and simplifying the equation to solve for the desired variable.
Yes, most formulas can be changed to solve for a different variable as long as the equation follows the rules of algebra. However, some formulas may require more complex steps and techniques to change the subject.
It is important to be careful when using inverse operations and to double check the new equation for any mistakes. It is also helpful to have a good understanding of the properties of algebra and how to manipulate equations before attempting to change the subject of a formula.
