Solve for n: 1/4 (n-2)=1/4n-1/2

alisha [4.7K]

Answer:

See below:

Step-by-step explanation:

So, we start off with the equation: $\frac{1}{4} (n-2) = \frac{1}{4}n-\frac{1}{2}$

If we simplify, we can use the distrubutive property to simplify the equation:

Here is how it goes:

$\frac{1}{4} (n-2) = (\frac{1}{4} * n )+(\frac{1}{4}*-2)$

So upon simplification of that, we get here: $\frac{1}{4}n + -\frac{1}{2}= \frac{1}{4}n-\frac{1}{2}$

Hm, somethings off, do you see that they are the same thing...

So, that means that there would be infinately many solutions.

You can plugin any number and you would get the same result!

Need help solving a practice question

liraira [26]

Answer:

x=10

Step-by-step explanation:

Using Pythagoras theorem

H^2=O^2+A^2

26^2=24^2+A^2

676= 576+A^2

676-576= A^2

100= A^2

square root both sides

10= A

Therefore, x=10
