7 = r^1/2 is the same as saying 7 = square root of r. So, to get rid of the square root sign on the r, you need to square it, and when you do something to one side of the equation, you have to do the same to the other side. So after squaring both sides, you get 49 = r.
All you do is divide 96 divided by 6. That is your equation. Then when you divide it, you find that he will put 16 on each shelf. All of the shelves will have the same number of books. The next one all you do is add all of them up and it will equal 43. So he has 43 dvd in total. Now if he wants to only keep eight of the dvds you subtract eight from 43. That equals 35. Now all you do is divide that by 5 to see how many he will give each friend. Once you're finished with that you find that he will give 7 to each friend.
So, the answers to each problem are 16 with the equation using distributive property 2(44 + 2) divided by 6 and 7.
I hope this helps:) Please give brainliest:)
Well, it might not be important for most problems but..
If you're dividing, and the answer is a repeat..
You can estimate.
Example - 2.678 | You can estimate it to 2.68 and use that as an answer instead of a very long answer that's repeated.
I hope this helps.
Answer:
Start by using your first factor, 1. Substitute "1" for each "x" in the equation: (1)3 - 4(1)2 - 7(1) + 10 = 0.
This gives you: 1 - 4 - 7 + 10 = 0.
Because 0 = 0 is a true statement, you know that x = 1 is a solution.

You could model a strait road by using a segment addition postulate. For instance, if you are between point A and B you could calculate how much future you need to go by subtracting the length of the road by the distance you have traveled. Also, segment addition postulate can be used with City Water Lines or Sewer Lines. They can be used to calculate how much pipe is damaged and needs to be replaced.
