Drag and drop 1.4 and k to their correct positions on the number line.

Drag and drop the label “Sum” to the sum of 1.4 and k.

Answer 1

The answer above me makes no sense the picture is all messy

Explanation:

Answer 2

For this case we have the following definition:
The additive inverse of a number is the opposite of that number, that is, the additive inverse of a number x is - x. The sum of a number and its additive inverse is equal to zero.
We have then:

`1.4 + k = 0`
From here, we clear the value of k.

`k = -1.4`
Then, we place the values on the number line.
