Answer: 2m/s
Step-by-step explanation:
The boat goes twice as fast down the river, which means it goes twice as slow up the river.
Because the river flows at 2m/s, I think the answer is 2m/s
30-10=20
20-10=10
or
10+20=30
Answer:

Answer:
They will have the same solution because the first equation of System B is obtained by adding the first equation of System A to 3 times the second equation of System A.
Step-by-step explanation:
System A
2x + y = 5 --> (1)
−4x + 6y = −2 --> (2)
(1) + 3×(2)
-10x + 19y = -1
System B
−10x + 19y = −1 --> (1)
-4x + 6y = −2 --> (2)
Answer:
I don't know what you mean but if it is 2+19 the answer is 21. But if it is 2+1 the answer 3
