Answer: Subtraction property of equality.

Step-by-step explanation:

n + 9 = -3

You are trying to move 9 from one side to the other. To do that, you have to do the inverse operation and subtract nine from both sides. Your result would be n = -12.

The volume of a right rectangular prism is 573.3 cm³. The length of the right rectangular prism is 7.35 cm and the height is 16.

IgorLugansk [536]

The width of the right rectangular prism is 4.8. You multiply 7.35 by 16.25 and then you divide 573.3 by that answer. So, 573.3 ÷ 119.4375 = 4.8. Hope this helped
