Answer:
6 sides
Step-by-step explanation:
the interior angle + the exterior angle = 180°
let x be the exterior angle then 2x is the interior angle and
x + 2x = 180
3x = 180 ( divide both sides by 3 )
x = 60
the exterior angle = 60°
the sum of the exterior angles of a polygon = 360°
since the polygon is regular the the exterior angles are congruent, then
number of sides = 360° ÷ 60° = 6
Answer: 44.7
Step-by-step explanation:
Mean= total sum of data set/ number of data set
313÷7
Mean = 44.7
26 green apples
if you do 0.4 * 65 you get <u>26</u> which is 40% of 65

Answer:
x = 1/10
Step-by-step explanation:
2/x -2 = 3/2x +3
Add 2 to each side
2/x -2+2 = 3/2x +3+2
2/x = 3 /2x +5
Subtract 3/2x from each side
2/x -3/2x = 3 /2x - 3/2x +5
2/x - 3/2x = 5
Get a common denominator
2/x *2/2 -3/2x =5
4/2x - 3/2x = 5
1/2x =5
Multiply each side by 2x
1 /2x * 2x = 5 *2x
1 = 10x
Divide each side by 10
1/10 = 10x/10
1/10 =x
