Answer:

Answer ? = 9

Step-by-step explanation:

the commutative property of addition just means that when adding (say counting numbers) you can reverse the order. It won't matter how you do the addition. For example

5 + 9 = 9 + 5

Some number systems don't like that very much. So the number you put in for the question mark is 9.

A vessel full of water weighs 16.5kg. when the vessel is half full, it weighs 10.5kg. find the weight of the empty vessel

omeli [17]

We know that
A vessel full of water weighs 16.5kg
when the vessel is half full, it weights 10.5kg
so
16.5 kg-10.5 kg=6 kg is the weight of half water
the weight of full water=6kg*2------> 12 kg
so
the weight of the vessel=A vessel full of water-the weight of a full water
the weight of the vessel=16.5 kg-12kg=4.5 kg

the answer is
the weight of the vessel is 4.5 kg
