7x - 8 = 8 + 3x
7x - 3x = 8 + 8
4x = 16
x = 16/4
x = 4
Answer:

Step-by-step explanation:
we know that
The probability that it will hit a point in the outer (yellow) ring is equal to divide the area of the yellow ring by the total area of the target
step 1
Find the area of the yellow ring
![A=\pi [7^{2} -5^{2}]](https://tex.z-dn.net/?f=A%3D%5Cpi%20%5B7%5E%7B2%7D%20-5%5E%7B2%7D%5D)

step 2
Find the total area of the target
![A=\pi [7^{2}]](https://tex.z-dn.net/?f=A%3D%5Cpi%20%5B7%5E%7B2%7D%5D)

step 3
Find the probability

Convert to percentage

Answer:
(-6,-4)
Step-by-step explanation:
So there actually is really easy way to solve this problem(that many people will never teach you for some weird reason).
Find difference between two points first in x and y direction.
X difference = (-3 - (-8)) = 5
Y difference = (-1 - (-6)) = 5
Multiply 2/5 to each difference
X difference 5 * 2/5 = 2
y difference 5* 2/5 = 2
just add the two number to First point(point A)
-8 + 2 = -6
-6 + 2 = -4
(-6,-4)
