This is a tough one. Thanks to everyone who helps
VladimirAG [237]

Step-by-step explanation:

Hello there!

A good first step is to fill the t=blanks with 2 and 4.

Then proceed as follows:

3 |2x+4|=24\\3(2x+4)=24\\2x+4=\frac{24}{3} \\2x+4=8\\2x=8-4\\2x=4\\x=2

And there you are! Feel free to comment with questions, and have a grwat day!

I NEED HELP!

Answer:

So, there are 3 cards in total, which means your pobability of picking one card out of the 3 cards is %33.33. So the probability of picking a 7 is 1/3. Because the other two numbers are greater than 7, and you already picked 7 so you cannot pick it again, the probabitily of pick a number greater than 7 is %100, or 3/3.

I hope that answers your question! :)
