The length of Albert's rectangular are listed below.
trapecia [35]
A. Length - 100 ft Width - 50 ft is the measurement of Tony's backyard.

Albert's Perimeter = 2(l+w) = 2(40+20) = 2(60) = 120 ft.

Tony's Perimeter = 120 ft * 2.5 = 300 ft
Tony's length = 40 ft * 2.5 = 100 ft
Tony's widht = 20 ft * 2.5 = 50 ft

To check tony's perimeter:
P = 2(l + w) = 2 (100 + 50) = 2 (150) = 300 ft.

Solve the system using substitution and describe your steps. <br> x=y-3 <br> 2x+y=12
Misha Larkins [42]
X = y - 3 (equation 1)
2x + y = 12 (equation 2)

Substitute equation 1 into equation 2, replacing every x value with equation 1

2(y - 3) + y = 12

Now, distribute the 2 inside the brackets and simplify.
2y - 6 + y = 12
3y = 18
y = 6 (divided both sides by 3)

Substitute y back into equation 1 to find x.
x = 6 - 3
x = 3

Verify that these are correct by substituting them into equation 2.
2(3) + 6 = 6 + 6 = 12

Therefore, x = 3 and y = 6
