A boat moves at a rate of 40 mph in Stillwater if the rivers current flow in a rate of 4 mph how long does it take a boat to travel 22 miles upstream?
upstream rate: 40 mph - 4 mph = 36 mph
how long: 22 miles/36 mph = 0.6 h = 36 minutes
I'm guessing you're trying to simplify the equation since there is no other information lol
[(2x+y)-3]
So basically when you are trying to simplify equations you have to add the same variables together (In this case X & Y) But since there are no alike variables there really is nothing to add
So your answer would be 2x+y-3
Hoped this helped
Answer:
y= 1/3x -3
Step-by-step explanation:
For the y-int for 8x-2y=6 is (0, -3).
For the slope of 3x-9y=9 is 1/3.
50 x 9 = 450
450 - 4 = 446
446 - 7 = 439
Answer:
56$
Step-by-step explanation:
