Answer:The combined weight of the bulldozer and dirt is 12 8/10 tons
Explanation:
The weight of the empty bulldozer is 5 8/10 tons. We would simplify the weight of the bulldozer by converting 5 8/10 tons to improper fraction, it becomes (50 + 8)/10 = 58/10 tons.
It scooped up 7 1/10 tons of dirt. Converting the weight of the dirt to improper fraction, it becomes
(70 + 1)/10 = 70/10 tons
The combined weight of the bulldozer and dirt would be the weight of the bulldozer + the weight of the dirt. It becomes. It becomes
58/10 + 70/10 = (58 + 70)/10 =
128/10 = 12 8/10 tons
