Answer: Option 2.

Step-by-step explanation: 3x−4y=6

3x−4y+4y=6+4y

3x/3=4y+6/3

x=4/3y+2

7x-6y=9

7(4 /3 y+2)−6y=9

10 /3 y+14=9

10 /3 y+14+−14=9+−14

10 /3 y /10 /3 = −5 /10 /3

y= −3 /2

x= 4/ 3 y+2

x= 4 /3 ( −3 /2 )+2

x=0

x=0 and y= −3 /2

A car travels 14km in 25mins . Find out how far the car can travel in 5 hours if the speed remains the same ?

jekas [21]

<h3><u>Answer :- </u></h3>

168 km ...

<h3><u>Explanation :- </u></h3>

It is given that the car travels 14km in 25 minutes..

Now , assume that the distance the car travel in 5 hours be x..

Since 1 hour = 60 minutes..
5 hours = 300 minutes ..

• Thus , The two given statements are :-

14km -----------------> 25 minutes..
And, x km -------------> 300 minutes..

The distance travelled by car and the time taken by the car is directly proportional to each other....

$\frac{14}{25} = \frac{x}{300}$

$= x = 168km$

• Hence , Car can travel 168km in 5 hours ..

Hope this helps you :)
