The equation is: 27.46 = 1.95x + 2.50
The answer is 12.8
The sum of the interior angles of a polygon with N sides is (N-2) x 180 degrees.
For a 30-gon, the sum of interior angles is (28) x (180) = <u>5,040 degrees</u>.
It makes no difference whether or not the polygon is convex at every vertex.
The unknown digit is 7 because 6.471 is greater than 6.470 and less than 6.48.
Answer:
i really dont knok but my guess is yes
Step-by-step explanation:
So the equation is x + 2x + 5= 29
Here are the steps -5 -5
-----------------------
3x = 24
Divide both sides by 3 so you get
x = 8
Then look back at the question, the second number has to be twice that number plus 5
So the 1st number is 8 The second # is 2(8)+5= 21
