I am not sure what does that question mean by simplify. If it means not to solve and just arrange;
You can divide the whole of the equation to m^2
Then you get;
19/m -4 +4
And you can divide the whole equation to 4 then you get;
19/4m -1 +1
You can also write as ;
(1/m * 19/4) - 1 + 1
Let's get the data out of the problem:
Nv = 18
Ov = 12
Now, we can apply in this equation that relates the new and the old values:
i = Nv / Ov
i = 18 / 12
i = 1.5
Now, we just consider what has passed from 1, and this is 0.5, converting to percentage it is:
p = 0.5 . 100
p = 50%
The increase was 50%.
Hope it helps.
Answer:

Step-by-step explanation:
h + 4 ≤ 20
Subtract 4 from both sides.
h ≤ 20 − 4
Subtract 4 from 20 to get 16.
