The sum of angles in a regular n sided polygon:

(n - 2)*180

(n - 2)*180 = 11520

(n - 2) = 11520/180

(n - 2) = 64

n - 2 = 64

n = 64 + 2

n = 66

Polygon has 66 sides.

Solve the following system of equations by the substitution method. 10x+10y=1.
Klio2033 [76]

Answer:

Since one equation already has one variable isolated(x), it gives you a "value" to input into the other equation to use to solve for the other variable(y).

10(y-3) + 10y = 1

10y - 30 + 10y = 1

20y - 30 = 1

20y = 31

y = 31/20 or 1.55

Now you can use this value to solve for x in one of the original equations.

x = (31/20) - 3

x = -29/30 or -1.45

Hope this helps!

Solve equation <br> -8n+7(8+3n)=-16+4n
spin [16.1K]

Answer:

<h2><u><em>-8</em></u></h2>

Step-by-step explanation:

Solve equation

-8n + 7 * (8 + 3n)= -16 + 4n

-8n + 56 + 21n = -16 + 4n

13n + 56 = -16 - 56

13n -4n = -16 - 56

9n = -72

n = -72 : 9

<u><em>n = -8</em></u>
