<span>A rectangular soccer field is twice as long as it is wide. If the perimeter of the soccer field is 300 yards , what are its dimensions?
I know the basic formula is 2W+2L=300 but i am not sure where to go from there...
-----
Equations:
2W + 2L = 300
L = 2W
----
Substitute for "L" and solve for "W":
</span><span>2W + 2(2W) = 300
6W = 300
W = 50 yds (width)
----
Solve for "L":
L = 2W
L = 100 yds (length)
========================
Cheers.

9/100 = x/90
Cross multiply to get 810 = 100x
Divide both sides by 100 to get x = 81 inches
Answer:
y = 11/20x -50
Step-by-step explanation:
100y−39,000=55(x−800)
Distribute
100y−39,000=55x−44000
Add 39000 to each side
100y−39,000+39000=55x−44000+39000
100y = 55x -5000
Divide each side by 100
100y/100 = 55x/100 - 5000/100
y = 11/20x -50
This is slope intercept form
where 11/20 is the slope and -50 is the y intercept
For the most part, the cross-section formed is a <em>trapezoid</em>, but if the slice passes through the apex of the pyramid, that shape is a <em>triangle</em>.

36/39 or 12/13 is th answer to that
