Answer:

x = 68

Step-by-step explanation:

The formula for calculating the sum of interior angles of a polygon is: (n - 2) x 180° (where n is the number of sides)

This polygon has 5 sides, so the sum of the interior angles:

(5 - 2) x 180° = 540°

To find x, add together all the angle expressions, equate to 540 and solve for x:

U + V + W + Y + Z = 540

(x - 8) + (3x - 11) + (x + 8) + x + (2x + 7) = 540

Gather like terms: x + 3x + x + x + 2x - 8 - 11 + 8 + 7 = 540

Combine like terms: 8x -4 = 540

Add 4 to both sides: 8x = 544

Divide both sides by 8: x = 68

For problems 12 - 14, Determine whether each sequence appears to be an

marshall27 [118]

Step-by-step explanation:

⇒12)It is an arithmetic sequence.

d=2-1=3-2=4-3=1

a(n) = a +(n-1)d

a(n) = 1+(n-1)1

The next three terms:

a(6) = 1+(6-1)1=6

a(7) = 1+(7-1)1=7

a(8) = 1+(8-1)1=8

⇒13)It is an arithmetic sequence.

d=0-3=-3-0=-6+3=-3

a(n) = a +(n-1)d

a(n) = 3+(n-1)-3

The next three terms:

a(5) = 3+(5-1)-3=-9

a(6) = 3+(6-1)-3=-12

a(7) = 3+(7-1)-3=-15

⇒14)It is not an arithmetic sequence.

⇒15) a(50) = 10 +(50-1)5

Aaron needs 24 inches of copper wire for an experiment. The wire is sold by the centimeter. Given that 1 inch = 2.54 centimeters

tatiyna

$\frac{1}{2.54} =\frac{24}{x}$

Multiply both sides by 2.54.

$1=\frac{24}{x} (2.54)$

$= \frac{60.96}{x}$

Multiply both sides by x.

x = 60.96

Hence, Aaron needs 60.96 centimeters of wire.
