Answer:
b = 2.28571428571 or 2.29 or 2 2/7 or 16/7
Step-by-step explanation:
b + 8b - 5 - 2b = 16
b + 8b - 5 - 2b + 5 = b + 8b - 2b
b + 8b = 9b - 2b = 7b
7b = 16
7b / 7 = b
16 / 7 = 2.28571428571 or 2.29 or 2 2/7 or 16/7
9-(-5)=
9 + 5 (because - - = +)
14
thus 9-(-5) = 14
2 1/4 inches
1/4 per 1 foot so if there are 9 feet it would be 9/4 then converte that to a proper fraction which is 2 1/4
