Y= (x-6)/2. Plug that for of first equation into;
Answer:
Math is fun dot com. All one word. (With .)
For other straight lines, I’m assuming you are supposed to graph the intersections, just use the two point form to get the rise and run. The rise / run is the slope. Usually called ‘m’ in formula form. Plug each Straight line formula into the Same web page above and it will graph the line for you. Be sure each line is in the [Y = mX+b ]
Format. Y is the up, X is the over, m is the slope. (Change in Y divided by change in X) (like stairs), and ‘b’ is the Y intercept. That means where the line crosses the Y (up) axis.
Step-by-step explanation:
If we now that 4y equals to x, that means we can replace x with 4y.
Therefore we can write: 4y+2y = 12
We can summarize that to 6y = 12.
If we divide both sides with 6, you get y = 2
In order to solve for x, we can use the second equation and just replace y with value we just got (y=2).
We can write: x+2*2=12
Now you move 2*2 (which is 4) to the other side: x=12-4
Now you get: x = 8

Answer-
You can read 2 groups of three books.
Step-by-step expression-
3 times 3 is 9. Since 9 is bigger than 8, you multiply 3 by 2. 3 times 2 is 6. Therefore, you can only read 2 groups of 3 books. Happy studying :))
N₁*$0.10 + n₂*$0.25 = $2.25
n₁ + n₂ = 12
-----------
This means that:
n₁ = 12 - n₂
And:
(12 - n₂)*$0.10 + n₂*$0.25 = $2.25
12*$0.10 - n₂*$0.10 + n₂*$0.25 = $2.25
$1.20 + n₂*$0.05*(5-2) = $2.25
$1.20 + n₂*$0.05*3 = $2.25
$1.20 + n₂*$0.15 = $2.25
n₂*$0.15 = $2.25 - $1.20
n₂*$0.15 = $1.05
n₂ = ($1.05)/($0.15)
n₂ = 7
If n₂ = 7:
n₁ + 7 = 12
Therefore, n₁ = 5.
