Question

Why do you think it might be useful to rearrange formulas before solving for one of the variables? (Relate your answer to the Celsius and Fahrenheit formulas and examples.)

Answer 1

It’s easier to find the solution to a variable when that variable is by itself on one side of the equal sign. Rearranging formulas before substituting values for each variable makes calculations more straightforward. With this approach, we only need to perform operations such as multiplication, division, addition, and subtraction on one side of the equal sign, and we simplify instead of solving by using the properties of equality.

Answer 2

It makes the solution of the equation easier

Explanation:

Here we have the formula relating Celsius and Fahrenheit given as follows;

`C = (5* (F - 32))/(9)`

From the above Celsius to Fahrenheit equation, we have that to solve for F we rearrange the formula as follows

`C =(5F)/(9) - (32* 5)/(9)`

Which is the same as

`C =(5F)/(9) - 17(7)/(9)`

It is then seen that rearranging the equation between Celsius and Fahrenheit makes it easier to solve for either °C or °F.
