Whoever answers these three questions correctly first will get brainliest ! asap

4. -8
5. 24
6. I can't see it properly so if it's ÷ answer is 9 if it's - answer is -70

4. original = 12 degrees
Rose by 8 degrees
12+8= 20
drop by 28 degrees
20-28= -8 degrees.
So the answer is -8°.

5. (-6) * (-4) = 24

when a negative times a negative, the result will turn positive.

6. I believe it's a divide sign, ➗
-63 / -7 = 9
when a negative divides by a negative, the result turns positive.

But if it's a positive sign, than it's -70.
-63 + -7= -70
