Question

Mary set the temperature outside on two different days are in absolute value of 20. Case it was wrong because the temperature on the two days were different. Can marry be correct? Explain your reasoning

Answer 1

Yes, Mary is correct.

Explanation:

We are told that Mary set the temperature outside on the two different days in absolute value of 20.

Now, absolute value simply means the distance of a number to the left and right of zero on a number line.

So going to the left of zero implies we will have a negative value of the number and going to the right of zero implies we will have a positive value of that same number.

Thus, applying that explanation to the question, it means the temperature was 20 degrees to the left and right of zero on the number line.

Which means that she obtained 2 values which are -20 and +20 degrees temperature.

Therefore, she is correct because with the absolute value she will get 2 different temperatures.
