Answer:
The expression is not equivalent to other three is 9(n-9) .
Option (B) is correct .
Step-by-step explanation:
Take first expression
= -9 -7n + 16n
= 9n-9
Take second expression
= 9(n-9)
= 9 × n - 9 × 9
= 9n - 81
Take third expression
= n-9+8n
= 9n-9
Take fourth expression
= 9n-9
Therefore expression is not equivalent to other three is 9(n-9) .
Option (B) is correct .

Answer:
current speed = 12 mph
Step-by-step explanation:
distance / rate = time
time upstream + time downstream = 26
25 / (13-c) + 25 / (13+c) = 26 ( c = current speed)
solve for c = 12 mi/hr
