Answer:
x=5, y=6. (5, 6).
Step-by-step explanation:
-6x+6y=6
-6x+3y=-12
---------------
simplify -6x+6y=6 into -x+y=1 and y=1-(-x)=1+x
-6x+3(1+x)=-12
-6x+3+3x=-12
-3x=-12-3
-3x=-15
3x=15
x=15/3
x=5
-6(5)+6y=6
-30+6y=6
6y=6-(-30)
6y=6+30
6y=36
y=36/6
y=6
First, find the area of the lacrosse field on the drawing. It is a rectangle, so you can just multiply the length and width:
A=5.5*3
A=16.5 in. squared
If 1 inch represents 20 yards, then 1 inch squared is going to represent 400 yards squared for area. Now we can set up a ratio:
16.5/x=1/400
x=6,600 yards squared
