Step-by-step explanation:
5 - n/2 = 12
10/2 - n/2 = 12
n = (12 × (-2)) + 10
n = (-24) + 10
n = <u>-1</u><u>4</u>
Let's prove it :

Conclusion :
5 - n/2 = 12
5 - (-14/2) = 12
and
n = -14
You have to set up a proportion so 2 over 3= x over 60. So multiply 2 times 60= 120 divided by 3 which is 40
The volume of the stones will be 384 inch³.he volume of the stone is found by subtracting the volume before stones and the volume after stones in the container.
<h3 /><h3>What is volume?</h3>
The term “volume” refers to the amount of three-dimensional space taken up by an item or a closed surface. It is denoted by V and its SI unit is in cubic inch.
Volume before the stones are put in the container is;

The volume after the stones are put in the container is;

The volume of the stone is found by subtracting the volume before stones and the volume after stones;

Hence,the volume of the stones will be 384 inch³.
