Question

the equation $d = \frac{m}{v}$ can be used to calculate the density, $d$, of an object with mass, $m$, and volume, $v$. which is an equivalent equation solved for $v$?\
\bigcirc \\; dm = v\
\bigcirc \\; \frac{d}{m} = v\
\bigcirc \\; \frac{m}{d} = v\
\bigcirc \\; m - d = v

Explanation:

Step1: Start with given density formula

$d = \frac{m}{V}$

Step2: Multiply both sides by V

$d \times V = \frac{m}{V} \times V$
$dV = m$

Step3: Divide both sides by d

$\frac{dV}{d} = \frac{m}{d}$
$V = \frac{m}{d}$

Answer:

$\boldsymbol{\frac{m}{d}=V}$ (corresponding to the third option)
