The equation [tex]d = \frac{m}{V}[/tex] can be used to calculate the density, [tex]d[/tex], of an object with mass, [tex]m[/tex], and volume, [tex]V[/tex]. Which is an equivalent equation solved for [tex]V[/tex]?

A. [tex]d m = V[/tex]
B. [tex]\frac{d}{m} = V[/tex]
C. [tex]\frac{m}{d} = V[/tex]
D. [tex]m - d = V[/tex]



Answer :

To solve the equation [tex]\( d = \frac{m}{V} \)[/tex] for [tex]\( V \)[/tex], follow these steps:

1. Start with the given equation:
[tex]\[ d = \frac{m}{V} \][/tex]

2. Our goal is to isolate [tex]\( V \)[/tex]. To do this, multiply both sides of the equation by [tex]\( V \)[/tex] to get rid of the fraction:
[tex]\[ d \cdot V = m \][/tex]

3. Now, to isolate [tex]\( V \)[/tex], divide both sides of the equation by [tex]\( d \)[/tex]:
[tex]\[ V = \frac{m}{d} \][/tex]

So, the equation [tex]\( d = \frac{m}{V} \)[/tex] solved for [tex]\( V \)[/tex] is:
[tex]\[ V = \frac{m}{d} \][/tex]

Among the given options:
- [tex]\( dm = V \)[/tex] is incorrect because it does not correctly isolate [tex]\( V \)[/tex].
- [tex]\( \frac{d}{m} = V \)[/tex] is incorrect because it does not have the correct relationship between [tex]\( d \)[/tex], [tex]\( m \)[/tex], and [tex]\( V \)[/tex].
- [tex]\( \frac{m}{d} = V \)[/tex] is correct and matches our derived equation.
- [tex]\( m - d = V \)[/tex] is incorrect as it does not come from rearranging the original equation properly.

Therefore, the correct equivalent equation solved for [tex]\( V \)[/tex] is:
[tex]\[ \frac{m}{d} = V \][/tex]
