Question

evaluate-9 when 20 is placed in the box ​

Answer 1

Answer: I believe the answer is 11.

Step-by-step explanation:

If you put 20 in the box then you with see "20-9" so it only makes sense for the answer to be 11. It also says the answer at the bottom I am pretty sure so that might just be an example.

Answer 2

Hey There!

--------------------------------------

Answer: The only thing that would be put in the box would be 20.

--------------------------------------

Why? Because the question isn't specific enough to where it only states to solve 20 - 9 and fill in the boxes. The question only states so solve it with 20 being put in the box. Nothing else would equal to 11.
