Can someone solve for x??

Mathematics

Sum of interior angle of polygon: S = (n-2) * 180°,

where n is number of sides and where S is total degrees.

With 6 sides, n = (6-2)*180 = 720°

Then set all of the interior equations equal to the sum, or

720 = 5x + 4x+2 + 5x+6 + 2x-2 + 3x+5 + x-10

720 = 20x + 1

719 = 20x

x = \frac{719}{20} = 35.95

Which list shows the numbers in order from least value to greatest value
Alina [70]
The answer is H

Explanation: what I did was change all of the numbers into decimal form so that we can compare them easier, -2 1/2= -2.5, -2.47 stays the same, -2/5 becomes positive .4 because the entire fraction is negative, you can look at it like -2/-5 and a negative divided by a negative is a positive, And then 5 stays a 5, And 21/4 equals 5.25 therefore your answer is H

Oh and by the way if you don’t know how to turn a fraction into a decimal you simply divide the top number by the bottom number for example 1/2 you take 1 and divide it by 2 which gives you .5 or 12/13 = .923076 hope this makes sense and that this helped

The points (−4, −3) and (3, y) lie on the same line.
drek231 [11]

Answer:

y= 11

Step-by-step explanation:

\boxed{slope =  \frac{y _{1} - y_2 }{x_1 - x_2} }

Substituting the coordinates and value of slope:

\frac{y - ( - 3)}{3 - ( - 4)}  = 2

\frac{y + 3}{3 + 4}  = 2

\frac{y + 3}{7}  = 2

Multiply both sides by 7:

y +3= 2(7)

y +3= 14

Subtract 3 from both sides:

y= 14 -3

y= 11
