The second showing had begun at 5:25. And there had been a 1/2 hour (30 minutes) break before it. So we substract this break from 5:25 and we get 4:55 - the time when the first showing had ended.
So the first showing had begun at 2:30 and had ended at 4:55. By substracting 2:30 from 4:55 we get 2:25 - that's the duration of the video.
The answer is 2 hours and 25 minutes.
Hopefully this helps if not use Photomath
Answer:
x = 83.2
Step-by-step explanation:
Let the unknown number be x
-90 * (x - 83) = x + (-99)
-90x + 7470 = x - 99
Subtract x from both sides
-90x - x + 7470 = x - x - 99
-91x + 7470 = -99
Subtract 7470 from both sides
-91x + 7470 - 7470 = -99 -7470
-91x = -7569
Divide both sides by -91
x = 83.2
