I think you can find it graphically by points through a table you create like:
let x = 0, and find the value of y
for example for the first equation when we let x = 0 you find y = 6 and be in the form of (0,6) then draw them or you can let x = -2 or -3 , etc as you like
to be more accurate you can find 3 pionts and start graphing them
these two equations are straight lines and they will intersect in a point
The area of the room must equal the sum of the areas of the tiles...
20*30=n(2*3)
600=6n
n=100
So 100 tiles are needed.

The number "x" is given by:
Therefore, we have:
Answer:

Step-by-step explanation:
we have to divide the given distance by 3.
Then we will be able to find the distance between markers.
Given distance is

Since, there are three markers,
So, we have to divide this distance by 3
So, the distance between markers is-

So, the distance between marker is

Now, we have to convert this into mixed number.
Then, the distance is-

Answer:
13pounds =$7
13/7pounds = $1
1.85pounds=$1
