Answer:

13/20 simplified and 52/80 not simplified

Step-by-step explanation:

So this is pretty simple.

First: Write out the problem on a piece of paper.

Second: Cross out all the 1's and 2's because those represent a made field goal.

Third: Count the number of 3's, 4's, 5's, and 6's.

Fourth: That gets you to 52. This is your numator.

Fifth: Count the total number of 1's, 2's, 3's, 4's, 5's, and 6's. That is 80. That is now your demoinoator.  

Sixth: 52/80 is simplified to 13/20.

Answer: B. 4

Hope this helps :)

Answer:

B. 4

Step-by-step explanation:

So the question is z + 7 = 11 right.

So let us begin, First if you add 3 + 7 that will make 10 which is what we are looking for. Next 4 + 7  will make 11 that is your answer but let us see if there is another same answer.  5 + 7  makes 12 which is close but not the answer. and the last one is 2 + 7  makes 9 which is not even close to the question. So your answer is B.  4 (4 + 7 = 11).
