4(-8x + 5) = -32x - 26
-32x + 20 = -32x - 26
-32x +32x = -20 - 26
0 = -46

Answer:
1620°
Step-by-step explanation:
The formula for finding that measure is ...
sum of interior angles of n-sided convex polygon = 180°×(n -2)
For n=11, this is
sum = 180°×9 = 1620°
_____
Another way to get there is to remember that the sum of <em>exterior</em> angles is always 360° for a convex polygon. Then the total (interior + exterior) of the angles of an n-sided polygon is 180°×n. Subtracting the sum of exterior angles gives the total of interior angles: 180°×n -360° = 180°×(n -2).

Answer:
22
Step-by-step explanation:
If there are n children, the number of candies in the first distribution is ...
3n +1
If the same number of candies is distributed to the same n children, then the second distribution tells us ...
2n +8 = 3n +1
7 = n . . . . . . . . . subtract 2n+1. This is the number of children.
The number of candies is ...
3(7) +1 = 22
There were 22 candies in total.
The racer take 4 hours (between 8:00 to 12:00) to race 3/4 of 6 miles
3/4 of 6 miles = 18/4 = 4.5 miles
4 hours ⇒ 4.5 miles
1 hour ⇒ 4.5 ÷ 4 = 1.125 miles
The time taken to complete 6 miles = 6 ÷ 1.125 = 16/3 hours = 5.3 hours
