Answer 1

Hi your answer is B on edge

Answer 2

B. a conversion factor

Step-by-step explanation:

The expression "1 in. = 2.54 cm" is called a conversion factor.

With this expression inches can be converted to centimeters.

Inversely the expression can also be used to convert centimeters to inches

By rearranging the equation we get

`(1)/(2.54)\ inches=1\ cm\\\Rightarrow 1\ cm=0.394\ inches`

The statement which shows the equal nature of two different expressions is called an equation

Rule of thumb is a general approximation of a result of a test or experiment.
