Solve each formula for n.
2n = 4xp-6
3m-n=4s
r/n+2=p
t=100(n+3)
pv/nR=T
8a+2=6b
In the first example, divide both sides of the equation by 2
In the second example, add n to both sides of the equation.
Try these yourself. They aren't that hard. We will be glad to critique your work.
There is no "n" in the last example.
1. 2n=4xp-6
Divide 2 from both sides:
n=2xp-3
2. 3m-n=4s
Subtract 3m from both sides:
-n=-3m+4s
Divide -1 from both sides:
n=3m-4s
For the last one I meant -
8a+2n=6b
If 8a+2n=6b, then
2n = 6b - 8a
n = 3b - 4a
You seem to understand this pretty well.
A=1/2h(b+b) find the hieght if the base is cm and 8cm and the area is 56cm.
Yes, in the first equation 2n = 4xp - 6, you can solve for n by dividing both sides of the equation by 2. This isolates the variable n on one side of the equation:
2n / 2 = (4xp - 6) / 2
This simplifies to:
n = 2xp - 3
In the second equation, 3m - n = 4s, you can solve for n by adding n to both sides of the equation. This cancels out the -n term on the left side and isolates the variable n:
3m - n + n = 4s + n
The -n and +n terms cancel out, and you're left with:
3m = 4s + n
To solve for n, you can subtract 4s from both sides of the equation:
3m - 4s = 4s + n - 4s
The 4s and -4s terms cancel out, and this simplifies to:
3m - 4s = n
Now n is isolated on one side of the equation.
In the third equation, r/n +2 = p, you can solve for n by subtracting 2 from both sides of the equation:
r/n + 2 - 2 = p - 2
The +2 and -2 terms cancel out on the left side, and this simplifies to:
r/n = p - 2
To solve for n, you can multiply both sides of the equation by n:
n * (r/n) = n * (p - 2)
On the left side, the n and (r/n) terms cancel out, and this simplifies to:
r = n * (p - 2)
Now you can divide both sides of the equation by (p - 2) to solve for n:
r / (p - 2) = n
In the fourth equation, t = 100(n + 3), you can solve for n by first distributing the 100 to both terms inside the parentheses:
t = 100n + 300
Then, you can solve for n by subtracting 300 from both sides of the equation:
t - 300 = 100n + 300 - 300
This simplifies to:
t - 300 = 100n
Now, you can divide both sides of the equation by 100 to solve for n:
(t - 300) / 100 = (100n) / 100
The 100 and 100 terms cancel out on the right side, and this simplifies to:
(t - 300) / 100 = n
Finally, in the fifth equation, pv/nR = T, there is no "n" variable involved. So, you don't need to solve for n in this equation.
I apologize for the confusion with the last equation. If the equation is 8a + 2n = 6b, you can solve for n as follows:
First, subtract 8a from both sides of the equation:
8a + 2n - 8a = 6b - 8a
The 8a and -8a terms cancel out on the left side, and you get:
2n = 6b - 8a
Then, you can divide both sides of the equation by 2 to isolate the variable n:
(2n) / 2 = (6b - 8a) / 2
The 2 on the left side cancels out, and you're left with:
n = 3b - 4a
That's the solution for n in this equation.
