Answer:
x = 111
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 7 , then
sum = 180° × 5 = 900
Sum the interior angles and equate to 900
x + 139 + 121 + 125 + 126 + 158 + 120 = 900
x + 789 = 900 ( subtract 789 from both sides )
x = 111
Answer:
B. 11/18
Step-by-step explanation:
Solve using algebra.
x = 0.611111...
10x = 6.111111...
10x - x = 6.111111.. - 0.61111111..
9x = 5.5
x = 5.5/9
x = 11/18
Answer:

Hope it helps :)
It take 23 mins for the drive
He needs to reach the airport by a quarter before 6
a quarter before 6 = 5.45
So he needs to leave 23 mins before 5.45
23 mins before 5.45 = 5.22
