Answer:z=47
Step-by-step explanation:
You're doing this because if you have z-31=16 you have to + 31 to 16 which would give you 47 then that would be a one step equation
z-31=16
you would make a line between the equal sign so it is organized then plus 31 to sixteen then that would get you to 47
Answer:

Step-by-step explanation:
To find
of the volume, we first must know the total volume.
The formula to find volume:

We know the length is 25m, we know the width is 20m and we know the depth is 5m.
So, we can substitute them into the equation:

Now we know the total volume, we can find out the volume when it is
full:

Therefore, our final answer is
.
There are a number of ways you can write the piecewise function. Here is one of them:

It could also be something like
p(t) = 7t + 3.50×max(0, t-40)
where the max(x,y) function returns the larger of x or y.
