Usually divide by 2.
Divide 2800 by 12. Then multiply that answer by 2.30. That's the formula. Now do it yourself.
Studies may show its 21 and it may be true but come on we all know when you add 10 and 9'its 19. You learn it in 1st or 2nd grade.
I only play Xbox. I wish I had a good computer to play minecraft pc.
It's my best subject but not very fun but not bad either.
In real life No, but in math I am not sure.
I agree it's y=-2
If you are a "know it all" it's 21 or the proper answer 19.
my school is crazy about the "9+10=21" thing.
