<span>You did not include the equations that you want to assess whether they can be used to solve for the radius (r).
Likely, the equation of the circumference, C = 2*Pi*r is included, if so => r = C / (2*Pi).
If you round Pi to 3.14, the equation may be written r = C / 6.28.</span>

Answer: x = 
</h3>
Step-by-step explanation:
- Subtract 6kx from 30kx to get 24kx = 8.
- divide both sides by 24kx:
= 
- That leaves us with .
Answer:
The second one
Step-by-step explanation:
if you do the math you can see that the value of x is the second one. I got it right on edge
Answer:
n= 3/5
Step-by-step explanation:
This can be easily done by cross-multiplying(and also beneficial to get rid of fractions):
(5n+1)(2) = 1(8)
10n +2 = 8
10n = 8-2
10n=6
n = 6/10
Simplify:
n = 3/5
Hope this helps!
