<span>8 - 2b = -2/3(12b + 6)
8 - 2b = -8b -4
8 + 4 = -8b + 2b
12 = -6b
b = -12/6
b = -2
So, your final answer is b = -2</span>

Answer:
Team's rowing speed in still water: 11.8 miles per hour.
Speed of the current: 3.4 miles per hour.
Step-by-step explanation:
Let r represent team's rowing speed in still water and speed of current be c.
Rowing speed with current would be and rowing speed against current would be .
We have been given that a rowing team rowed an average of 15.2 miles per hour with the current. We can represent this information in an equation as:
We are also told that rowing team rowed an average of 8.4 miles per hour against the current. We can represent this information in an equation as:
Upon adding equation (1) and (2), we will get:
Therefore, teams's rowing speed in still water was 11.8 miles per hour.
Upon substituting in equation (1), we will get:
Therefore, speed of the current was 3.4 miles per hour.
Answer:
22.22%
Step-by-step explanation:
Well first let's find the difference between 22 and 18. 22 - 18 = 4. There's a 4 point difference, so now we need to find out how much 4 is of 18. 4 is 22.22% of 18.
