Answer:
Option 3rd is correct
29 alternative schools are in the county
Step-by-step explanation:
Let x be the alternative schools are in the county.
As per the statement:
In a certain county, the number of charter schools is 6 less than twice the number of alternative schools.
⇒Number of charter school = 2x - 6
It is also given that we know that there are 52 charter schools in the county.
⇒Number of charter school =52
then;
![2x-6 = 52](https://tex.z-dn.net/?f=2x-6%20%3D%2052)
Add 6 to both sides we have;
![2x= 58](https://tex.z-dn.net/?f=2x%3D%2058)
Divide both sides by 2 we have;
⇒x = 29
Therefore, 29 alternative schools are in the county
