-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.
Answer:
1.66667
Step-by-step explanation:
4 x ? = 12 ? = <u>3</u>
so,
z x ? = 5
5/<u>3</u> = 1.6666667
-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

Answer:

Step-by-step explanation:
The sum of the measures of the interior angles of each convex n-sided polygon is always equal to

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

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

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

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

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

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