Answer: a
Step-by-step explanation:
Answer:
Length: 6 ft
Width: 4 feet
Step-by-step explanation:
Length: L
Width: 2L - 8
2L + 2(2L - 8) = 20
2L + 4L - 16 = 20
6L = 36
L = 36/6
L = 6
W= 2(6)-8 = 4
so you have your two equations 3x+7=5x-23 and solve for x which is your "number" leaving the answer to be <u>x=15</u>
7 hours X 60 minutes = 420 minutes
420 minutes + 20 minutes = 440 minutes
