Question

Help me pleeeeeease my test is gonna end in 30 minutes

Answer 1

Answer:

i believe it is -7 degrees. 13-20=-7

pro tip: "big minus small takes the sign of the big" is how i remember negative numbers.

20 is the bigger than 13, and when you subtract them you get 7. 20 has a negative, so 7 takes "the sign of the big", making it -7

Answer 2

Answer:

The answer is -7

Step-by-step explanation:

Because if you started at positive 13 and it dropped 20 degrees, it would be negative 7.
