Answer:
Length = 160 and width = 55 yards
Step-by-step explanation:
Perimeter = 2L + 2W where L = the length and W = the width.
L = 3W - 5 (given).
So substituting for L is the formula for the perimeter:-
2(3W - 5) + 2W = 430
6W - 10 + 2W = 430
8W = 440
W = 55 yards.
So the Length L = [430 - 2(55]) / 2 = 160 yards.

Step-by-step explanation:
We are given:

To simplify this inequality, we can add 2 to all three sides. When we do that, we are left with:

After we simplify that, we can divide all sides by -6. Here is what we get:

When you simplify, your final answer will be:

Answer:
(x, y) =(-6,4)
Step-by-step explanation:
3x-y=-28
-5x-4y=-10
y=3x+28
-5x-4(3x+28)=-10
y=3x+28
-5x-12x-112=-10
y=3x+28
-17x=-10+112
y=3x+28
-17x=102
y=3x+28
x=102/(-17)
y=3x+28
x=-6
y=3*(-6)+28
x=-6
y=-24+28
x=-6
y=4
x=-6
(x,y)=(-6,4)
Idk if it is more complex but wouldn't it be just 7
