Answer: 7
Step-by-step explanation:
Because to find the median to find the numbers in a triangle.
Let b and s be the velocity of the boat and stream respectively....
3(b-s)=27
b-s=9
b=9+s we will use this in the second equation....
2(b+s)=30
b+s=15, now use b found above in this to get:
9+s+s=15
2s+9=15
2s=6
s=3, and since from earlier b-s=9, b=9+s so
b=12
So the speed of the boat is 12mph and the stream is 3 mph
Answer:
4/5
Step-by-step explanation:
slope = (difference in y)/(difference in x)
slope = (-5 - 3)/(-5 - 5)
slope = -8/(-10)
slope = 4/5
