Question 851637: The perimeter of a regular pentagon measures 10x-25.Find the length of one side

You can put this solution on YOUR website! The formula for finding the perimeter of a pentagon is 5x = Perimeter, where x is the length of each side. So, in order to solve, we need to set up as an equation:
5x = 10x - 25
Since we need to get x by itself on one side of the equation, we can first subtract 10x from both sides, giving us
-5x = -25
Finally, divide both sides of the equation by -5, which will give us x (the sides of the pentagon):
x = 5
Therefore, the length of one side of the pentagon is 5.
