Answer:
88
Step-by-step explanation:
The sum of the interior angles of a triangle is 180 degrees
2x-9+3x+x+3=180
6x-6=180
6x=186
x=31
A=2(31)-9
A=62-9
A=53
A billion is 9 zeroes
1.96 is already less than 10 and greater than or equal to 1 so
1.96 times 10^9 is answer
A is answer
The third term of the sequence is 20
Since it takes one hour to fly 230 miles, and we are looking for the number of hours, we can divide the number of miles we are given by the speed. In this case, we would divide 1380 by 230 to get 6. This means it would take 6 hours for the plane to fly 1380 miles.
