Answer:
D. 1800°
Step-by-step explanation:
The given polygon has 12 sides.
The formula for finding the sum of the interior angles of an n-sided polygon is given as, ( n − 2 ) × 180.
Where n is the number of sides of the polygon.
Thus, the sum of the interior angles of the 12 sided polygon given above is:
(12 - 2) × 180
= 10 × 180 = 1800°
<em>Sum of the measures of the interior angles of the 12-sided polygon is D. 1800°</em>
A proportional relationship is just a linear relationship where b = 0, or to put it another way, where the line passes through the origin (0,0).
Answer:
15
Step-by-step explanation:
Answer:
the solutions are {-2, 3}
Step-by-step explanation:
First combine the constants 2 and 17:
3|2x-1|+2=17 => 3|2x - 1| = 15
Next, divide both sides by 3. We get:
3|2x - 1| = 15 => |2x - 1| = 5
We want to solve for x, so divide all three terms by 2 as follows:
|x - 1/2| = 5/2
This equation has two solutions. We regard 1/2 as the "center." The equation tells us that x is either 5/2 greater than this 1/2 or 5/2 smaller:
x = 1/2 + 5/2 = 6/2, or x = 3
and:
x = 1/2 - 5/2 = -4/2 = -2
Thus, the solutions are {-2, 3}
