Answer:

answer: the crews rowing rate is 6 mph and the rate of the current is 3 mph

Step-by-step explanation:

v the crew rowing rate

u rate of the current

downstream  v + u = 13.5/1.5 = 9 mph

upstream      v - u = 13.5/4.5 = 3 mph

u = 9 - v

v - ( 9 - v ) = 3

v - 9 + v = 3

2 v = 12

v 6 mph,   u 9 - 6 = 3 mph

- 2/5(20x -15) can you plz help me
Alex17521 [72]

Answer:

Step-by-step explanation:

First I just made -2/5 into a decimal because I like to work with decimals better (which equals -.4)

Then I times everything separately in the parenthesis and got -8x+6

Next you move the 6 over to the left side of the equals sign which would make the equation be -6 = -8x

Lastly you divide the -8 from -6 and you get X = 3/4
