The order of division determines the numerator and the denominator and this can effect the value. And example of this:
3/2 = 1.5
2/3 = 0.6667
Whereas, multiplication is not affected by the order:
2 x 3 = 6
3 x 2 = 6

Division is not associative, as if you look at one of the operands to a nest of divisions, the result will vary either in proportion to it or inversely to it depending on whether it's to the right of an odd or even number of divisions. And the basic associative law changes the number of operations the rightmost operand is to the right of by 1.

How to solve y in -(y+9)=10
Allisa [31]

Answer:


Step-by-step explanation:

- (y+9) = 10


Multiply through by -1 gives us


y+9 = -10


Subtract 9 from both sides


y = -19


That's your answer.


If you work it through it satisfies the equation.


That is:


- (-19 +9) = 10


-(-10) = 10


10 = 10

professor190 [17]
Well, from 2008 to 2010 is just 2 years, so let's say the initial amount is the 19300 from 2008, how many will it be in 2010?

\bf \qquad \textit{Amount for Exponential Growth}\\\\&#10;A=I(1 + r)^t\qquad &#10;\begin{cases}&#10;A=\textit{accumulated amount}\\&#10;I=\textit{initial amount}\to &19300\\&#10;r=rate\to 20\%\to \frac{20}{100}\to &0.20\\&#10;t=\textit{elapsed time}\to &2\\&#10;\end{cases}&#10;\\\\\\&#10;A=19300(1+0.2)^2

Solve the absolute value inequality.
Alex Ar [27]

Answer: k ≤ -4 or k ≥ \frac{4}{3}

<u>Explanation:</u>

                      | 3k + 4 | ≥ 8

3k + 4 ≥ 8             or                3k + 4 ≤ -8

<u>       -4</u>  <u> -4  </u>                              <u>       -4</u>    <u>-4 </u>

3k       ≥ 4              or                3k       ≤ -12

<u>÷3       </u> <u>÷3  </u>                              <u> ÷3       </u>   <u>÷3 </u>

k        ≥ \frac{4}{3}            or                 k       ≤  -4

Identify the equation that dose not belong with the other three explain your reasoning pls
arsen [322]
If you take a moment and solve each equation (find the value
of the letter in each one), it'll jump out at you.

Here, let me do it for you.  Why should you tire yourself.

5x = 20 . . . . . x = 4

4b = 7 . . . . . . b = 7/4

8w = 32 . . . . . w = 4

12y = 48 . . . . . y = 4

The second equation is not like the others.
It's the only one where the letter is not equal to  4 .
