Answer:
5
Step-by-step explanation:
Ok so there is 60 minutes in an hour and you have 107 minutes so
107-60 = 47 ( 60 has become an hour)
So we are left with 47 minutes, so add the hour to 7:45 which will make it 8:45 pm
Then add 15 to make it 9:00 pm ( 47 - 15 = 32)
And so then add 32 minutes to 9:00 pm
Answer is 9:32 p.m.
3x² -x+4=0
