What is -9-2(7-1) simplified??? please i really need help FAST

vichka [17]

To evaluate two fractions being divided, you must turn the right fraction into a reciprocal. That means you must put the bottom number at the top and then put the top number on the bottom (you’re basically switching them).

8/13 / 3/2

Now, once you turned the other number into a reciprocal, you multiply across. The top number times the other top number and do this to the bottom numbers, too.

8/13 * 3/2 = 24/26

You found the answer, 24/26. But as you can see, it’s not one of the choices. That’s because you need to simplify.

24/26 / 2/2 = 12/13

12/13 is your answer, or choice C!

I hope this helped. Comment below if you have any questions.

If Gage gets 40 bucks a month how much months would it take him to get 300 bucks.

USPshnik [31]

Answer:

7 to 8 months / most probably 8 months

7.5 months to be exact

Step-by-step explanation:

Hi there!! Let's work!

So lets Break it down,

Given: $40 every month

Prove: How many months till he has in total $300

----------------------------------------------------------------------------------------------

<h2>We need to multiply the number of months to 40 to get 300</h2>

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

<h3>So lets refer to a multiplication chart to make it easier:</h3>

||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

<h3>Here is an example of the equation we will use:</h3>

<u>400 x (months) = $300 / (or how much ever we get)</u>

```````````````````````````````````````````````````````````````````````````````````````````````````````````````````````

We have 2 final equations because we don't have a straight forward answer. (Refer to explanation below)

40 x 7 = 280

and

40 x 8 = 320

---------------------------------------------------------------------------------------------------------

So in problems like these we have to think like we would in real life, if you have an option you can write 7 to 8 months or you should write 8 instead of seven since they may be asking for a specific amount of months and after 8 months Gage will reach (surpass) his goal of $300 by $20.

What number goes into 5,6,7 & 9?

Allisa [31]

The Least Common Multiple of 5, 6, 7, and 9 goes into 5, 6, 7, and 9. The Least Common Multiple of 5, 6, 7, and 9 is 630. If you multiply that by 2, 3, 4, and so on, you get a never-ending set of numbers that go into 5, 6, 7, and 9.

Please Help! :) <br> Solve for X. The polygons in each pair are similar.

Diano4ka-milaya [45]

Answer:

x=2.65

Step-by-step explanation:

First, we need to figure out how much the length of the sides is changing between the equations. In this case it is changing by a factor of 2.5. Now we need to work backwards. First use this equation:

$4x-5*2.5=14$
