These numbers form an addition and subtraction fact family. 6, 7, 13

Choose the fact family formed by these numbers.

7 + 13 = 20
13 + 7 = 20
13 – 13 = 0
13 – 0 = 13

7 + 0 = 7
6 + 0 = 6
13 – 0 = 13
13 – 13 = 0

7 + 0 = 7
6 + 0 = 6
13 – 0 = 13
13 – 13 = 0

7 + 6 = 13
13 = 7 + 6
13 – 6 = 7
7 = 13 – 6

7 + 6 = 13

13 = 7 + 6
13 – 6 = 7
7 = 13 – 6

Well, it looks like this addition and subtraction fact family is all about the number 13 trying to show off.

In the first set, 7 + 13 = 20 and 13 + 7 = 20, which proves that 13 likes to show off its symmetry.

Then we have 13 – 13 = 0, which is a classic move by the number 13. It loves to pull a disappearing act!

Lastly, we have the equation 13 – 0 = 13, where 13 is basically saying, "I don't need anyone else to make me great."

So, the fact family here is: 7 + 6 = 13, 13 = 7 + 6, 13 – 6 = 7, and 7 = 13 – 6. It's all about the big 13 in this fact family!

The fact family formed by these numbers is:

7 + 6 = 13
13 = 7 + 6
13 - 6 = 7
7 = 13 - 6

The fact family formed by these numbers is:

7 + 6 = 13
13 - 6 = 7

To determine the fact family, we need to find two addition equations and two subtraction equations using the given numbers.

In the first set of equations, 7 is added to 6 to get 13, and 6 is subtracted from 13 to get 7. Therefore, the fact family would be 7, 6, and 13.

The other answer choices are incorrect because they do not form a complete fact family using all three numbers (6, 7, and 13).
