What is the value of x knowing that the interior angle of this regular polygon is (-134x+516+2x)?
Answers
Based on the calculations, the value of x for this regular polygon with the given interior angle is equal to 3.
What is a polygon?A polygon can be defined as a two-dimensional geometric shape that comprises straight line segments and a finite number of sides. Also, some examples of a polygon include the following:
TriangleQuadrilateralPentagonHexagonNonagonOctagonNote: The number of sides (n) of a hexagon is 6.
In Geometry, the sum of the interior angles of both a regular and irregular polygon is given by this formula:
Sum of interior angles = 180 × (n - 2)
Sum of interior angles = 180 × (6 - 2)
Sum of interior angles = 180 × 4
Sum of interior angles = 720°.
Next, we would determine the value of x by using this formula:
Interior angle × Number of sides = Sum of interior angles
Substituting the parameters into the formula, we have;
(-134x + 516 + 2x) × 6 = 720
-134x + 516 + 2x = 720/6
-134x + 516 + 2x = 120
516 - 120 = 134x - 2x
396 = 132x
x = 396/132
x = 3.

This is because if she types 25 words in one minute then that means she can type 50 words in 2 minutes (just multiply by 2). The only person on the graph who can type 50 words in 2 minutes is Britt.

-2y - 3y + 8 = 8 -5y - 12
solve this equation fast please
Answers
What we need to do is cancel both like terms on both sides of this equation which is
8=8 and you remove them.
Then you are left with -2y-3y=-5y-12
What you need to do is add -2y-3y because they are like terms
Now you have -5y
Then you put -5y=-5y-12
So you have to now cancel equal terms on both sides of this equation which were “-5y=-5y”, then you turn them into a 0
Now you are left with 0=-12
Therefore the statement is false for any value of y.

Answer:
-17
Step-by-step explanation:
The sum of -2 and -9 is (-2) + (-9) = -2 - 9 = -11.
The sum of -7 and 13 is 13 - 7 = 6.
Hence, subtracting 6 from -11 would be -11 - 6 = -17.

A sports store is having a 20% off sale on skis. The original price of the ski is $560.00
The tax rate is 8.5%. What is the total cost of the skis?
Answers
Answer:
Total cost: 486.080$
Step-by-step explanation:
Original Price: 560.000$
Sale: 20%
Discount: 560.000$ * 20% = 112.000$
Discounted Price: 560.000$ - 112.000$ = 448.000$
Tax Rate: 8.5%
Tax: 448.000$ * 8.5% = 38.080$
Tax after Tax: 448.000$ + 38.080$ = 486.080$

D.

Answers
Answer:
the y-intercept is 8 and the slope is -4/3 .
Step-by-step explanation:
The y - intercept is (0, 8) and the slope is -4/3
What is the y-intercept?"It is the point at which the graph of the function intersects the y-axis"
What is slope?The slope of the line passing through points [tex](x_1,y_1),(x_2,y_2)[/tex] is,
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
For given example,
We can observe that the line of best fit on this scatter plot passes though points (0, 8) and (6, 0)
Using the slope formula,
⇒ slope = (0 - 8)/(6 - 0)
⇒ slope = (-8)/6
⇒ slope = -4/3
Also, we can observe that the line of best fit on this scatter plot intersects y-axis at point (0, 8)
So, the y - intercept is (0, 8)
Therefore, the y - intercept is (0, 8) and the slope is -4/3

However, I think the question is
