How do you solve 2x(x+3)=(x+1)(2x-5)

1 answer:

8 0

Distribute and get 2x^2+6x=2x^2+2x-5x-5
add like terms and get 2x^2+6x=2x^2-3x-5
subtract 2x^2 from both sides and get
6x=3x-5
subtract 3x from both sides
3x=5
divide both sides by 3
x=5/3

A boat travels 8 miles upstream in the same amount of time it can travel 12 miles downstream. In still water the speed of the bo

Anastaziya [24]

Answer:

1 mi/hr

Step-by-step explanation:

Given that:

Speed in still water, s = 5 mi/hr

Let speed of current = x

Time = distance /speed

Upstream (subtract speed of current) = 5 - x

Upstream time = 8 / 5 - x - - - (1)

Downstream (add speed of current) = 5 + x

Downstream time = 12 / 5 + x - - - (2)

Equate (1) and (2)

8 / (5 - x) = 12/ (5 + x)

8(5 + x) = 12(5-x)

40 + 8x = 60 - 12x

40 - 60 = - 12x - 8x

-20 = - 20x

x = 1

Spwed of current = 1 mi/hr

vova2212 [387]

Answer:

$40\%x + x = 14 \\ \\ \\ \frac{40}{100} x + x = 14 \\ \\ \\ \frac{4}{10} x + x = 14 \\ \\ 0.4x + x = 14 \\ \\ 1.4x = 14 \\ \\ x = \frac{14}{1.4} \\ \\ \\ x = \frac{140}{14} \\ \\ \\ x = 10$
