5/12 because 1/1 is a whole, 1, so all you have to do is 1 - 7/12.
Answer:
24
Step-by-step explanation:
8 16 24 32 40...
6 12 18 24 30 36....
24 and 24.
A = first piece, b = second piece, c = third piece
a + b + c = 47
b = 3a
c = 5a + 2
a + (3a) + (5a + 2) = 47.....combine like terms
9a + 2 = 47
9a = 47 - 2
9a = 45
a = 45/9
a = 5 ft
b = 3a.....b = 3(5)....b = 15 ft
c = 5a + 2....c = 5(5) + 2.....c = 25 + 2....c = 27 ft
longest piece (c) = 27 ft
