first, you'll have to write the opposite of the + symbol which is - and then you'll have to lose the 3 by substracting it with, so the equation will look like this: a/5= 8-3 not 8+3
a/5=5
after that step you'll have to multiply 5 from the equal sgin with the 5 that is divided by a, so the final equation looks like this:
A) 0 represents the surface of the pool. B) The height of the pool is 10 above the pool surface C) It should be -3 since it is going down so it is going to be a negative number and it is also below the pool's surface.
