How many minutes are there in 4 hours,30 minutes i will give you 12 points

There are 60 minutes in one hour. If we are trying to find how many minutes are in 4 hours and 30 minutes, we first need to find out how many minutes are in 4 hours.
To do that, we just need to multiply the amount of minutes in an hour by the amount of hours we have.

60 * 4 = 240

Then, we just add the remaining 30 minutes.

240 + 30 = 270

There are 270 minutes in 4 hours and 30 minutes.
Hope that helped! =)

First subtract 10 from both side
y^2+6y-16=0
(y+8)(y-2)=0
-8 and 2
