Answer: The required equation is

Thus, there are 71 students on the bus at the beginning of the route.
Step-by-step explanation:
Given: The number of students dropped off = 
The number of students remain on the bus = 
Let 'x' be the total number of students in the bus then we get the equation as

On adding 23 to 48, we get 71
Hence,
Therefore, There are 71 students on the bus at the beginning of the route.
Let the number of rows be x
rows = x
seats in each row = x + 20
total seats = 1344
x (x + 20) = 1344
x^2 + 20x - 1344 = 0
(x + 48)(x - 28) = 0
x = -48 (rejected, answer cannot be negative) or x = 28
Therefore,
x = 28
x + 20 = 48
Check:
Row = 28
Numbers of seat per row = 28 + 20 = 48
28 x 48 = 1344 (Correct)
Ans:There are 48 seats per row
Answer:
1.57 radians
Step-by-step explanation:
Divide both sides by 360, you get 1° = π/180. This means 70° is equal to (70)(π/180). Then simplify this, and 70° = (7π)/18 radians, or approximately 1.221730476396 radians. This seems reasonable because 90°, is a quarter circle and (1/4) of 2π is π/2, which is approximately 1.57 radians.
