Answer:

two coordinates would be (3,5) & (9,15)

Step-by-step explanation:

5/3 x 9= 45/3= 15

and written in coordinate form it is (9,15)

5/3 x 3= 15/3= 5

written in coordinate form it is (3.5)

A fisherman traveled in a boat from point N upstream. After having traveled 6 km, he stopped rowing and 2 hour 40 min after firs

Nat2105 [25]

Answer:

The speed of the river's current is 4.5 km/hr.

Step-by-step explanation:

Given : A fisherman traveled in a boat from point N upstream.

After having traveled 6 km, he stopped rowing and 2 hour 40 min after first leaving N, he was brought back to N by the current.

Knowing that the speed of the boat in still water is 9 km/hour

To find : The speed of the river’s current.

Solution :

Let the speed of current = x km/h

Speed of boat = 9 km/h

Thus, the speed in upstream = (9 - x) km/h

Also, the speed in downstream = x km/h (because the boat is stationary in downstream)

Total distance = 6 km ( from N to the point he reached )

Total time = 2 hours 40 minutes

$\text{2 hours 40 minutes}=2\frac{40}{60}=2 \frac{2}{3} \\\\\text{2 hours 40 minutes}=\frac{8}{3} \text{ hours}$

We know, $\text{Time} = \frac{\text{Distance}}{\text{Speed}}$

According to the question,

$\frac{6}{9-x}+\frac{6}{x}=\frac{8}{3}$

Taking LCM and 6 common

$6[\frac{x+9-x}{(9-x)x}]=\frac{8}{3}$

Take 6 to another side,

$\frac{9}{9x-x^2}=\frac{8}{3\times 6}$

Cross multiply,

$9\times 18=8\times(9x-x^2)$

$162=72x-8x^2$

Taking 4 common and cancel out

$4x^2-36x+81=0$

Solve quadratic equation by middle term split,

$4x^2-18x-18x+81=0$

$2x(2x-9)-9(2x-9)=0$

$(2x-9)(2x-9)=0$

$\Rightarrow 2x-9=0$

$\Rightarrow x=\frac{9}{2}=4.5$

Therefore, The speed of the river's current is 4.5 km/hr.

Write a system of equations and then solve by the method of any chose. Reserved seat tickets for the football game cost 4.00 eac

beks73 [17]

Answer:

General tickets were 1,356 and reserved tickets were 431

Step-by-step explanation:

Let general tickets be <em>g</em> and reserved <em>r</em>

r + g = 1787

4r + 3g = 5792

Use first equation to solve for r

r = 1787-g

Substitute r in the second equation by (1787-g);

4(1787-g) +3g = 5792

7148 - 4g +3g = 5792

Group the numbers on one side and the unknown variables on the other side and solve for g;

7148 - 5792 = 4g-3g

1356 = g

With g= 1356, find r using any of the first two equations;

r+1356 = 1787

r = 1787 - 1356

r = 431

Therefore, general tickets were 1,356 and reserved tickets were 431
