5(2y-4) - 3y = 1. 10y-20-3y=1. 7y-20=1. 7y=21. y =3. x = 2(3)-4. x = 2. x*y =6.
<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..
<h3><u>We know that , </u></h3>
- The distance travelled by car and the time taken by the car is directly proportional to each other....
<h3>So , </h3>


• Hence , Car can travel 168km in 5 hours ..
Hope this helps you :)
Ok so first plug in y for in the equation 2x-2y=12
Therefore 2x - 2(x -6)=12
Then distribute the two to the x and the -6
2x-2x+12=12
The 2x's cancel leaving you with
12=12
From there you could subtract the 12 from both sides to get 0=0, I assume
B. The line is given from 0 to 8 hours which is the x-axis (domain). and 0 to 175 gallons, which is the y-axis (range).
It is prime because there aren't any numbers that multiply to 9 and add to -8
