7.5
Cross multiply (4•x) and (5•6) and get 30=4x
X=7.5
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.
Answer: (4,12) or (1/3) simplified
The common denominator is already there 12 is the common denominator!! :)
5.692 is a terminating decimal because the decimal stopped at the digit of 2.
Hope this helps!
