What number can you divide -12 by?
OpenStudy (rainbow_rocks03):
2?
OpenStudy (anonymous):
d. 60
because if you reverse it, -5x-12=60
so its 60/-12=-5
easy :D
OpenStudy (rainbow_rocks03):
thx.

Yeah 2 and you can also divide 60 by 2 . Which will give you a positive number divided by a negative number. Positive/negative is a negative.

ok so for number 8 you'll once again reverse it to division instead of multiplication, -9.24/2.8=-3.3
so the answer is c. -3.3
OpenStudy (anonymous):
same for number 9, reverse again,
5.8x2.2=12.76
so your answer is d. 12.76
