I’ll give brainliest please help!! A canoe travels 9 miles per hour downstream and 1 mile per hour upstream.

Let x represent the canoe's speed with no water current in still water) and y

represent the speed of the water current, in miles per hour. Then the situation

can be represented by this system of equations:

x + y = 9

x- y = 1

Choose the two correct options.

A. The speed of the canoe in still water is 4 miles per hour.

B. The speed of the water current is 5 miles per hour.

C. The speed of the water current is 4 miles Rer

hour.

D. The speed of the canoe in still water is 5 miles per hour.

Maybe the answer is 20mm. all i really did was just multiply, which is obvious.

First, think of what you know. you know that the number t the end of the equation will need to be subtracted because it is the money he lost from buying the lawn mower. and your first two weeks have negative profit, so that tells you that c and d are wrong. now you can plug any of the weeks into a and b to see which one works. i'll start with plugging week 1 into a.this isn't right because it says your answer for week one should be -90.so now we need to try the same thing with b.this one got you the right answer, (sometimes if you only check with one of the weeks multiple will work so you need to check with more of the weeks, but it worked out fine here)this means that b is the correct answer.let me know if you need more clarification. i hope this : )
