1.)
Starts with 40:10, then cuz you have 80 buns, you need to x2, so it would be 20 cubes
2.)
I don’t know, sorry
3.)
4:2 and 60 in total
so 4+2 is 6 and 60/6 is 10
so it would be 40:20 so 20
hope this helps :)
The Associative property.
4g+3y+9=total of 16 and subract one green ballon, so 15. If picking one probability is 1/15
When you substitute x with 2 you get 2(2)+2 so 4+2 is 6.
So when x is 2 y will be 6.
You can also see it in th diagram place your ruler on 2 in the x axis and you can see the lines passes through 6
