1) First, you would need to create an equation for this problem. Let x represent the unknown percentage.

=

Next, you would cross multiply.
185x = 3,500
Now, all you would have to do is isolate the x. To do this, you would divide both sides by 185.
x = <span>
18.918%Your answer was correct!
2) </span>First, you would need to create an equation for this problem. Let x represent the unknown 85%.

<span> = </span>

<span>
</span>Next, you would cross multiply.
100x = 16150<span>
</span>Now, all you would have to do is isolate the x. To do this, you would divide both sides by 100.
x = 161.53) First, you would need to create an equation for this problem. Let x represent the unknown percentage.

=

Next, you would cross multiply.
128x = 2,400
Now, all you would have to do is isolate the x. To do this, you would divide both sides by 128.
x = 18.75%I hope this helps!
Is there a picture for the question
It's B!------------------------------
Answer:
The answer is yes.
Step-by-step explanation:
All you have to do is substitute the y, which is 5, and the x, which is 2, into the equation. When you solve it the answer in the end will be 5=5, which means that point (2,5) does line on that line.
