John says that if one side of an inequality is 0 you dont have to reverse the inequality symbol when you multiply or divide both sides by a negative number find an inequality that you can use to disprove johns statement explain your thinking

W = 4

-5w < 0   (-20 < 0)   =true
divide both sides by -5
w < 0   (4 < 0)   =not true =Johns statement proven wrong   

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.

You can find the area of a rectangle by multiplying the length and height. so multiply 1/2*7/4(which is the simpler version of 1 3/4) and you get 7/8 as your answer.
