To find the average you add both of the numbers together and then divide by the number of numbers if that makes sense so 545 + 777 divided by 6 = 674.5

8×9=(5+y)×9 , what is y?
Step2247 [10]
8 * 9 = (5 + y) * 9
multiply 8 and 9

72 = (5 + y) * 9
use the distributive property

72 = 45 + 9y
subtract 45 from both sides

27 = 9y
divide both sides by 9 to isolate the variable

y = 3

Given:

The expression is

\dfrac{2}{a-2}-\dfrac{8}{a^2-4}

To find:

The simplified form of the given expression.

Solution:

We have,

\dfrac{2}{a-2}-\dfrac{8}{a^2-4}

It can be written as

=\dfrac{2}{a-2}-\dfrac{8}{a^2-2^2}

=\dfrac{2}{a-2}-\dfrac{8}{(a-2)(a+2)}            [\because a^2-b^2=(a-b)(a+b)]

Taking LCM, we get

=\dfrac{2(a+2)-8}{(a-2)(a+2)}

=\dfrac{2a+4-8}{(a-2)(a+2)}

=\dfrac{2a-4}{(a-2)(a+2)}

=\dfrac{2(a-2)}{(a-2)(a+2)}

Cancel out the common factors.

=\dfrac{2}{a+2}

Therefore, the simplified form of the given expression is \dfrac{2}{a+2}.
