Five watermelons that weigh 1050 grams (g) each were placed on one side of a pan balance scale. Two of nine apples of equal weight, each weighing 4.5 kilograms (kg), were placed on the opposite side of that scale. How many more melons weighing 850 grams (g) each must be placed on the side of the apples to level the scale?
