(6b + 7)(5b - 9)
You can take 5 out of both of those, leaving 6b and 1.
6b^2 - 3b / 3b 6b^2 - 1 or ( 6b^2 - 3b) / 3b = 2b - 1 Or (6b^2 - 3b ) / 3b = 3b(2b - ) / 3b = 2b - 1
30b-18 = 12
30b and 32a are the same size for the cups but different bands 30b has a tighter band than 32a
6b-5a = 1
6b - 4 = 2
3b+6b=9b
-6b =15 -6b/-6 = 15/-6 b = -2.5
what you do is you write it like this 30b=41.10 and then you divide 30 on both sides and so it looks like this and then you get the answer 1.37 30b=41.10 ___ ____ 30 30 b = 1.37
11b + 6b = 17b
6B = 1446B/6 = 144/6B = 24Double Check your Answer6B = 1446(24) = 144144 = 144So 6B = 144 when B = 24.
