The mathematical property demonstrated by 7+9+3=7+3+9 would be the commutative property. This property states that in operations such as addition and multiplication, when you switch the order of the numbers around, the result will always be the same. In 7+9+3=7+3+9, no matter what order you put the numbers in, the answer will always be 19.
Answer:
82
Step-by-step explanation:
For this problem you would first round everything. 9.03 becomes 9, 19.87 becomes 20, 3.11 becomes 3 and 4.97 becomes 5. You then just do the problem. 9 + 20 = 29, multiplied by 3 makes 87, 87 - 5 = 82.
