Answer:
<u>585 Cubic Meters</u>
Step-by-step explanation:
Since the room is in the shape of a rectangular prism, to find the volume, you'll do Volume = Length * Width * Height
So, 65 * 3 * 3 = 585 Cubic Meters
<em>(its in cubic meters because it is measuring a volume of space)</em>
They hiked the same distance because they were hiking at the same rate.
I'm not good at graphing, but desmos.com is an online graphing calculator that works really well.
3x - 6y = -2
-6y = -3x - 2, divide through by -1
6y = 3x + 2, divide through by 6
y = 3x/6 + 2/6
y = x/2 + 1/3
