What is the value of n in the relationship 8n+9=-n+5

1 answer:

8 0

Subtract 5 from both sides.

$8n + 4 = -n$

Subtract 8n from both sides.

$4 = -9n$

Divide both sides by -9 to solve for n.

$- \frac{4}{9} = n$

The value of n is -4/9.

Find the sum of the interior angle measures of the green polygon,

Radda [10]

Answer:

The sum of interior angles of given polygon is 900°

Step-by-step explanation:

A regular polygon is a n-sided figure with n sides and the length of all sides is same.

In the diagram, we have a polygon with 7 sides.

The formula given is used to calculate the sum of interior angles of a polygon

$Sum\ of\ interior\ angles = (n-2)*180$

Here n is the number of sides of polygon

In the given polygon

n = 7

So,

$Sum = (7-2)*180 = 5*180 = 900$

Hence,

The sum of interior angles of given polygon is 900°

Math definitely isn't my greatest subject, if anyone knows how to do this and can explain it to me please help!

Law Incorporation [45]

Answer:

y-1 = 5/3(x-3)

Choice C

Step-by-step explanation:

slope = (y2-y1)/(x2-x1)

(3,1) (6,6)

m = (6-1)/(6-3)

m = (5/3)

the point slope form of a line is given by

y-y1 = m(x-x1)

You have point (3,1)

y-1 = 5/3(x-3)

Choice C
