Since 0.61m and 1.51m are like terms you can simply subtract them
![0.61m-1.51m=-0.9m](https://tex.z-dn.net/?f=0.61m-1.51m%3D-0.9m)
Then the equation would look like this.
![-0.9m=9](https://tex.z-dn.net/?f=-0.9m%3D9)
So to isolate m you would divide by -0.9 on both sides
![m=-10](https://tex.z-dn.net/?f=m%3D-10)

Step-by-step explanation:
....................
As already mentioned, the volume for a rectangular prism, namely a box in this case, is just the product of its dimensions, length * width * height.

now, as far as another one... hmm is easier if you post in the channel, that way I can include any graphs if needed or tables and such.
so, what happens if you double up the dimensions?

notice, how many times the new size is, is 8 times the original.
Answer:
18.50 * 20% = 3.7
18.50 - 3.7 = 14.8
