We know that
<span>20% --------------> were blue
</span><span>1/10---> 0.10----> 10%-------------->  were white
</span><span>40% ---------------> were silver
</span>
and 
<span>9 ---------> were gold
so
gold=100%-(20%+10%+40%)-------> 100%-70%------> 30%

30% ---------------------> is equal to 9
10% (</span>were white)<span>-------> X
X=10%*9/30%------> x=3

the answer is
3</span>

Answer:

<u>Given</u>

  • Equation 5x - y = 12

and

  • Inequality 5x - y > 12

<em>See the graphs attached</em>

To draw the graphs follow the rules we described in the previous questions.

  • 1. Identify x-intercept and y-intercept and connect them to have the line.
  • 2. Shade the region above or below the line for the inequality.

We see the only difference the expressions have is the equation or inequality symbols.

  • Equation symbol means the graph of the equation is a line.
  • Inequality symbol means the graph of this is a region above the same line, in our case the line is not a part of the covered region because it is "<".

We can state that the inequality excludes the line and includes only the region above the same line.
