Question

The regular pentagon have a perimeter of 18.8 units. What is the value of X?

Answer 1

What does x represent?

Answer 2

69 lmao haha

Answer 3

also on the bottom of the pentagon it says x-3 how do you solve it

Answer 4

Your going to make your equation like:
X-3=18.8/5
/ means divide*
Then divide 18.8 and 5 which gets you 3.76
Plus 3 away from 3 to cross 3 out but add 3 to 3.76 which gives you 6.76
X=6.76

Answer 5

X - 3 = 18.8/5 ( 5 is how many sides of a pentagon)
Your going to multiply both sides of the equation by 5, one the left side the expression should be 5x - 15 on the right 18.8 ( since the two 5s cancel each other out), then opposite operations add 15 on both sides, left d two 15 cancel out so just 5x is left, on right it should add up to 33.8( 5x = 33.8) Then divide by 5 on both sides . X = 6.76

Answer 6

•Givens
A regular pentagon has 5 sides.
Perimeter = 18.8
Each side labelled = x-3

The equation is…
5(x-3) = 18.8
Distribute 5 into x and 5 into -3
5x-15 =18.8
+15 +15
Add each side by 15.
-15+15 cancel each other out.
Leaving us with 18.8+15 which is 33.8

We take our 5x from earlier and drop down 33.8
5x = 33.8

Now divide each side by 5 to get variable ‘x’ by itself.
(/)- Division
5x/5 = 0
33.8/5 = 6.76
x=6.76
