-8≥-5x+2>-38
-10≥-5x>-40
2≤x<8 (when divided by a negative number, the sign changes from ≥ or > to ≤ or <)
so x is between 2 (include 2, a solid dot) and 8 (doesn't include 8, a hollow bubble)
the third choice is correct.

-3x =21<br> 1/3x =6<br> -1/2x =-7
Kitty [74]
-3x = 21
Divide -3 from both sides and you get x = -7

1/3x = 6
Divide 1/3 from both sides and you get x = 18

-1/2x = -7
Divide -1/2 from both sides and you get x = 14 (you get a positive answer from 2 negatives)

Dividing 1/3 is just multiplying by 3, and dividing -1/2 is just multiplying by -2

Find the sum of the measures of the interior angles of each of the following convex polygons: a pentagon, an octagon, a dodecago
TiliK225 [7]

Answer:

540^{\circ},\ 1080^{\circ},\ 1800^{\circ},\ 6840^{\circ},\ 9000^{\circ},\ 17640^{\circ}

Step-by-step explanation:

The sum of the measures of the interior angles of each convex n-sided polygon is always equal to

(n-2)\cdot 180^{\circ}.

1. A pentagon is 5-sided polygon, then the sum of the measures of the interior angles of pentagon is

(5-2)\cdot 180^{\circ}=540^{\circ}.

2. An octagon is 8-sided polygon, then the sum of the measures of the interior angles of octagon is

(8-2)\cdot 180^{\circ}=1080^{\circ}.

3. A dodecagon is 12-sided polygon, then the sum of the measures of the interior angles of dodecagon is

(12-2)\cdot 180^{\circ}=1800^{\circ}.

4. For 40-sided polygon the sum of the measures of the interior angles is

(40-2)\cdot 180^{\circ}=6840^{\circ}.

5. For 52-sided polygon the sum of the measures of the interior angles is

(52-2)\cdot 180^{\circ}=9000^{\circ}.

6. For 100-sided polygon the sum of the measures of the interior angles is

(100-2)\cdot 180^{\circ}=17640^{\circ}.
