Subtract 7a from both sides giving you 10=-5a and divide everything by 5. This gives you a=-2
Answer:
the answer is written in the picture.
Step-by-step explanation:
The tenths place, starting from the right, it gets higher going to the left. so the tenths place is only ten times greater than it.
The sum of the interior angles of any polygon is given by (n-2)180°, where n is the number of sides.
Also sum of all the exterior angles of any polygon is 360°
Given (n-2)180° = 3(360°)
=> n-2 = 6
=> n = 8.
Hence the number of sides of a polygon is 8
Sample Response: If the data is collected in a biased manner, the graph could be skewed. Also, if the number of observations is too small, the graph can be skewed. To ensure the data is not skewed, collect a large representative unbiased sample
