She had 12 cookies and her brother ate 9 of them ,how many did he leave out of her 12?
20+6x=32
subtract 20 from 20 and 32
6x=12
6x/6=12
6 cancels out
x=2
8/10 is greater than 63/100 because when 8/10 is turned into a percentage it is greater
Hello!
You can solve this algebraically
6(z + 6) = 3(2z + 12)
Distribute the 6
6z + 36 = 3(2z + 12)
Distribute the 3
6z + 36 = 6z + 36
Since both sides are the same there are in infinite amount of solutions
The answer is an infinite amount of solutions
Hope this helps!
