Solve for the variable m in the formula:

 $e=mc²$  
(This is Einstein's equations for mass-energy equivalence)

•  $m=ec²$  

•  $m=\frac{c²}{e}$  

•  $m=\frac{e}{c²}$  

•  $m=e-c²$  

Answer explanation

m is being multiplied by c², so we need to divide both sides of the equations by c² to give us  $m=\frac{e}{c²}$

Solve for the variable the variable H in the formula:

 $V=LWH$  
(Formula for the volume of a prism)

•  $H=V-LW$  

•  $H=VLW$  

•  $H=\frac{LW}{V}$  

•  $H=\frac{V}{LW}$  

Answer explanation

H is being multiplied by L and W, so to isolate H, we need to perform the inverse of multiplication to L and W, which is division. This leaves the formula of:
 $H=\frac{V}{LW}$
