Answer:
<u>900</u> black and white copies are printed.
Step-by-step explanation:
Given:
For every 9 black and white copies printed there are 2 color copies printed.
If there are 200 color copies printed.
Now, to find the number of black and white copies are printed.
Let the number of black and white copies printed be
As given, for every 9 black and white copies printed there are 2 color copies printed.
So, 9 is equivalent to 2.
If there are 200 color copies printed.
Thus, is equivalent to 200.
Now, to solve by using cross multiplication method:
<em>By cross multiplying we get:</em>
<em>Dividing both sides by 2 we get:</em>
Therefore, 900 black and white copies are printed.
We have
-2x-3y <12
For this case what you should do is to graph the following straight line:
-2x-3y = 12
Then, the solution will be the shaded region that satisfies the following inequality:
-2x-3y <12
In the shaded region you will find all the solution points.
