ANSWER
The substitution property of equality.
EXPLANATION
We know that:
![12x = 60](https://tex.z-dn.net/?f=12x%20%3D%2060)
and that
![x = 5](https://tex.z-dn.net/?f=x%20%3D%205)
Since x=5 or 5=x , we can substitute x for 5 wherever we see x in the given equation.
When we do that, we obtain;
![12 \bullet \: 5 = 60](https://tex.z-dn.net/?f=12%20%5Cbullet%20%5C%3A%205%20%3D%2060)
This is what we refer to as the substitution property of equality.
He should place the picture at 6.75 inches from the edge of the wall.
<u><em>Explanation</em></u>
According to the below diagram, O is the center of the wall and <u>AB is the distance of the picture from the edge of the wall. </u>
As the length of the wall is
inches or 31.75 inches , so the half length of the wall
inches.
Now, the length of the picture is
inches or 18.25 inches, so the half length of the picture
inches.
Thus,
inches
So, he should place the picture at 6.75 inches from the edge of the wall.
