Sorry lolz
125/186 cannot be simplified. It is already in simplest form.
It's 28. here's proof 1/4 is 7, 1/2 is 14, 3/4 is 21, and 4/4 is 28.
Number of faces: F=a+3
Number of vertices: V=2a
Number of edges: E=4a-1
V+F-E=2
Replacing V=2a; F=a+3; and E=4a-1 in the formula above:
(2a)+(a+3)-(4a-1)=2
Eliminating parentheses:
2a+a+3-4a+1=2
Adding similar terms:
(2+1-4)a+(3+1)=2
(-1)a+4=2
Solving for a. Subtracting 4 both sides of the equation:
(-1)a+4-4=2-4
(-1)a=-2
Dividing both sides by (-1)
(-1)a/(-1)=-2/(-1)
a=2
Answer: The value of a is: a=2
Answer:
4
Step-by-step explanation:
10/100=0.1
1% = 0.1
