Cost of 12 notebooks = $9
Ratio of number of notebooks to its price
= 12:9
= 4:3 <em>(because we reduced it to the simplest form by dividing both numerator and denominator by 3)</em>
Let the cost of 8 notebooks be x.
Then, 8:x = 4:3
=> 8/x = 4/3
=> (8×3)/4 = x
=> 24/4 = x
=> 6 = x
So, the cost of 8 notebooks is $6.

Answer:
consistent
Step-by-step explanation:
The two equations have different slopes, so they intersect at one point. That point is the solution. That makes this system of equations consistent.
Light travels at a speed of 299,792 kilometers per second; 186,287 miles per second. It takes 499.0 seconds for light to travel from the Sun to the Mars a distance called 1 Astronomical Unit.
