I hope this helps you
8=x+4
x=8-4
x=4
So first we add up all the marbles. Which would be 25. Then we look to see how many red marbles there are. There are 5. You have a 5/25 chance of drawing a red marble. But you can reduce that. So when it's all said and done you have 1/5 chance of drawing a red marble.
Hope this helps!
Answer:
Step-by-step explanation:
First, you need to find the GCF of both denominators.
That would be 21.
You would need to multiple the 7 in 4/7 by 3, to get to 21. That means you would also have to multiply 3 by the 4. You should get 12/21.
Do you same thing to 1/3.
After that you should get the 2 factions, 12/21 and 7/21
12/21 + 7/21 = 19/21
There isn't anyway to simplify it, meaning the final answer is 19/21.
It is 1million cas in not really that smart I wish I was smarter
