solve for x.
x+9y=18
Add -9y to both sides.
x+9y+−9y=18+−9y
x=−9y+18
solve for y.
x+9y=18
Add -x to both sides.
x+9y+−x=18+−x
9y=−x+18
Divide both sides by 9.
9y/9=−x+18/9
y=−1/9x+2
Answer:
The length of rectangular plot of land is 160 ft.
Step-by-step explanation:
L = 2 W (the length is twice the width)
P = 480 ft. (perimeter of rectangular plot of land)
L = ?
2. 2W + 2W= 480 ft >>> (2 times twice width=L) + 2W=480 ft.
4W + 2W= 480 ft >>>> 6W= 480 ft.
W= 80 ft.
L = 2. 80 = 160 ft. (Length is twice the width)
P= 2L + 2W (formula for the perimeter)
2. 160 + 2. 80 = 480 ft.
