Answer:
n = 16
Step-by-step explanation:

___
In general, you identify the terms containing the variable. Then figure out what is being done to the variable. Here, it is multiplied by 1/2 and then 3 is subtracted. You undo these operations in reverse order.
Undo the subtraction of 3 by adding 3. Undo the multiplication by 1/2 by multiplying by its inverse, 2. Of course, the rules of equality tell you that anything you do to one side of the equation must also be done to the other side.
You can consider it as "unwrapping the package". You start at the outside, the last operation applied, and work your way in.

Answer with Step-by-step explanation:
We are given that


Compare with the equation of circle

Where center of circle=(h,k)
r=Radius of circle
a.Center of circle=(0,0)
Radius=
units
Center of second circle=(3,3)
Radius of second circle=
units
b.Distance formula:
Using the formula
The distance between the centers of two circle
=
Hence, the distance between the centers of two circle =
units.
c.
Substitute x=-1 and -1


The circle must be tangent because there is just one point (-1,-1) is common in both circles and satisfied the equations of circle.
Step-by-step explanation:
4x+92+2x+4=180
6x+96=180
6x=84
x=14
