Kim had 120 cards in a box. she gave 6/10 of the cards to maddy. how many cards did kim have left in the box?

The number of cards Kim gave to Maddy was:
120 cards* (6/10)= 72 cards

120 cards- 72 cards= 48 cards

Kim had 48 cards left in the box.

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
