It will be +18.6
Because (-20.4) is a negative number
Imagine a number line you would need 20.4 to get back to 0 since you will start at negative 20.4
39-20.4 is 18.6
So you have 18.6 left which will be on the positive side so that’s the answer

Alex17521 [72]

Answer: The correct answer would be -85.


Step-by-step explanation: This is because the -5 becomes positive because it is inside parentheses.

This would make the expression: -425 ÷ 5.

-425 ÷ 5 is equal to -85.

Hope this helps and have a nice day! :)
