Answer:
-50x + 600 = 250
Step-by-step explanation:
10x + 60(10-x) = 250
10x + 600 - 60x = 250
-50x + 600 = 250
You divide 24 and 6 that's the answer

Answer:
Option B
Step-by-step explanation:
When moving with the current, the speeds of the boat and current will add up. The first situation can then be represented by:
9 = 0.5(x + y)
While opposing the current, the speeds will be subtracted. Forming:
9 = 1.5(x - y)
The second option contains this equation system, so it is correct.
