Answer
Rex weighs 7.78 kilograms.
Solution
First, convert 720 grams to kilograms. Since 1 kilogram = 1000 grams, 720 grams is 0.72 kilograms.
Pixie weighs 8.5 kilograms, so Rex weighs:
8.5 kilograms - 0.72 kilograms = 7.78 kilograms.
Rex weighs 7.78 kilograms.

Simplify this solution Beyond the Answer
Rex weighs 7.78 kilograms. To find Rex's weight, you simply subtract the 720 grams from Pixie's weight. First, convert Pixie's weight to grams: 8.5 kg = 8500 grams. Then, 8500 grams - 720 grams = 7780 grams. Finally, convert it back to kilograms: 7780 grams = 7.78 kg. Rex weighs 7.78 kilograms.
