Quadrilateral ABCD is a parallelogram with diagonals that intersect at point E. If AD=4w-5 DE=4 BE=x/2 BC=7w-17 solve for w.

"Suppose the leftmost digits of 2 numbers are 8 and 3. Can you tell which number is greater? Explain."
Mariulka [41]
No, without further information you can't tell which number is greater. This is because there could be any amount of other digits to the right, which changes the value of the leftmost digit depending on the number it is a part of. Hope this helps! :)
