Answer:
x= -8 and so y=35.....solving equation
Answer:
Solution:
the boat's speed in still water: x
The speed with current: (x+3)
The speed against current: (x-3)
The equation is
3(x+3) = 4(x-3)
x = 21 mph
The distance = 3*(21+3)= 72 miles
I choose (A)
Step-by-step explanation:
Combing like terms you have 0.25k - k = -0.75k
and 1.5 - 3.5 = -2.0
The answer would be -0.75k - 2.0
