Answer:
Step-by-step explanation:
I belive the answer would be 18.30$, because if 1 hat is 6.70$ you mutiply it by 13 and which is 87.10$ - 325$ overall and the which is 237.9 then diveied that by 13 and get 18.30$ for each ball?


Step-by-step explanation:

- <em><u>distribute</u></em><em><u> </u></em>4 through the parentheses


- move the <em><u>variable</u></em><u> </u>to the left hand side and change its sign

- move the <em><u>constant </u></em>to the right hand side and change its sign

- collect<em><u> like</u></em><em><u> terms</u></em>
<em><u>
</u></em>

- divide both sides of the equation by <em>-</em><em>5</em>

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:
coordinates of the other endpoint (14; -6)
Answer:
C. 24
Step-by-step explanation:
4!=24
Apply factorial rule: n! = 1 * 2 * 3 * ... * n
4! = 1 *2 * 3 * 4
1 *2 * 3 * 4 = 24
4! = 1 *2 * 3 * 4 = 24
4!=24
