Answer:
3 x n - 12 < 21
Step-by-step explanation:
Answer:
2y^2 + 18x
Step-by-step explanation:
<span>So there are 4 books
=> 1 physics
=> 1 chemistry
=> mathematics
=> Biology
These books needs to be place on a shelf.
Now, let’s find the probability of mathematics book to be placed on top.
Let’s analyze the problem
Probability => 1 mathematics book / 4 total books
P = Probability
P = 1 / 4
P = ¼ or 0.25
Thus, the probability of mathematics book to be placed on top inside the shelf
approximately is ¼ or 0.25.</span>
This is simple to solve as all we need to do is setup a basic equation. An equation that could represent this is

where x is equal to the amount of wire left on the reel.



Using this information, we can see that
there are 1,873 feet of wire left on the reel.
