oh 45 because 20/4 is 5 and 5+40 is 45
sloppycanada
  • sloppycanada
Yeah, 45 is the answer you want. Though< I could've done a better job at explaining it.
noahbred
  • noahbred
yes pliss
sloppycanada
  • sloppycanada
So the first thing I did was work with everything multiplied. -10 x 2 = -20 8 x 5 = 40
sloppycanada
  • sloppycanada
We can now rewrite our equation as follows - -20/(-4) + 40
noahbred
  • noahbred
and you have to remove the - right
sloppycanada
  • sloppycanada
Yes. You do. 20/4 + 40
sloppycanada
  • sloppycanada
Since you do division BEFORE you add. 20/4 = 5. 5 + 40 = 45
noahbred
  • noahbred
ohh and 5 goes int 20 4 times so its 5+40=45
sloppycanada
  • sloppycanada
Bingo!
