12.25x + 8.75y > = 90 (thats greater then or equal) <== ur inequality
<span>The perimeter is the sum of the side lengths, or x+y+z.</span><span> </span><span>The perimeter is 67.5 inches. </span>
1 mile= 5280 feet
1/5280= 4.25/x This is a proportion.
5280 * 4.25= 22440
22440/1= 22440
4 1/4 miles= 22440 feet
Hope this helps! :D
Plug in m/4 into the equation:

Solve the parentheses in the equation:



Your equation should now look like this:

The answer is
D.
you would add 3y+5y and get 8y=-20
then the slope would be 8/1 and your y-intercept would be -20
