Find the amount of change by subtracting the two quantities. Divide this number by the original (starting) quantity, and convert to percent form by moving the decimal 2 places to the right.
Corresponding sides on either side of ED are proprotional, so
(x+2)/112 = 62/99.2
x +2 = 112*62/99.2 = 70
x = 68 feet
I say, change 233% into a decimal which would be 2.33 and then multiply from there. Which would be -0.0699
<em>To solve for a variable, you have to isolate that variable onto one side.</em>
<h3>1.</h3>
Firstly, multiply both sides by 2: 
Next, divide both sides by a + b and <u>your answer will be: 
</u>
<h3>2.</h3>
For this, divide both sides by πr², and <u>your answer will be 
</u>
<h3>3.</h3>
Firstly, subtract both sides by 2πr²: 
Lastly, divide both sides by 2πr, and <u>your answer will be: 
</u>
A solution to a system
Is the point two lines cross each other.
3. The lines cross at y = 0 and x = 2, so the solution is x = 2
4. The lines do not cross so there are no solutions.
5. It looks like there is one line which means the two lines are identical so there are infinite solutions
