*sigh* you don't. Unfortunately. 😔

First, apply PEMDAS, then group the factors with the same coefficients together (x^2 goes with x^2, which there are none, x goes with x, et cetera), then do the divide and conquer thingie, except watch your convention signs. 

Here's how: 1.110 * 1000 -1.12x - 1.1x - x = (1.110 * 1000) - (1.12x + 1.1x + x) = 0

So that's: 1110 - 3.22x = 0

Solve it and you should get 344.7205, rounded off to the 4th decimal place. 

Hi :) it's blackskirthollywood.

If it's $$(-2)^2$$, then it's $$(-2*-2)^2$$ so the answer will be 2.

if it's $$-(2)^2$$, then it's $$-(2*2)^2$$ , therefore the answer is -2.

I think your question is first one.

Thanks!

Yup Chris

Melody, I know how sad it is to steal, but do you want to be remembered as the teen who party pooped a party back in high school, or be remembered as the awesome adult who allowed us to have a cookie party?

How do you do 625^1/4?

Use calculator with a power key (x^y) to get your answer.

In this case 625^1/4=5, which is the same as 4th root of 625.

1 2/3 + (-2/5)

1 2/3 is the same 5/3

Then we have 5/3 +(-5/3)

which equals to 5/3 - 5/3=0

Three -fourth of the 28 students in Mrs mobley class bought their lunches to school. What percent is equivalent to the part of Mrs mobley students that brought lunch

You are partly answering you own question!!

3/4 of 28 students=21 students

So, as a percentage of students that brought their lunches would be 75% of them!

Which is the same as 3/4 of them.

1.110 x 1000 – 1.12 x – 1.1x -x=0

This comes to 1110.98x=0

Divide both sides by 1110.98

You get x=0

how would you divide rational numbers if it was a fraction.

for example: (1/4) / (1/7)

The easiest way to do is to write down the 1st. fraction as it is:

So, (1/4) instead of divide it, use multiply and reverse the second fraction:

So, 1/4 X 7/1. Then multiply the 2 top numbers or 1 x 7=7. Then multiply the bottom 2 numbers or, 4 x 1=4

Then you put the first number, or 7 on top and the 2nd number or 4 on the bottom,

Thus: 7/4. And you re-write it as 1 3/4.

I got this from the insert drop down box - special characters - it is on the third row :)

12-5x=-13 

Step one: subtract 12 from each side of the equal sign... Therefore, -5x=-13-12. Simplify.

-5x=-25

Step two: get x by itself. So divide by -5 on both side of the equal sign... 

x=5

27 - 24/8   =

27 - 3   =

what is 8 fifths subtract one half?

8/5 - 1/2=16/10 - 5/10=16-5/10=11/10=1 1/10=1.10

What the prime factorization of 315

The prime factors of 315=3 x 3 x 5 x 7

Well, 9/9 is equal to one whole, so 1. That leaves you with 1 - (10+2). Always do perentheses first. So 10+2 is 12. Now you have 1 - (12). Which would be -11. You're welcome.

I'll take the American......looks like we're gonna' need a lot of cookies for that !!!

If 12-5×=-13, what would x be?

Move x to one side and the other numbers to the other,

So, -5x=-13-12=-25

-x=-25/-5 or

x=5

What do you mean by this?

Simple. drop the -2 down (because we wont be using it.), and divide 20 by 4 which is 0.2. So therefore, the answer is -2.2

Answer is y=n/2*(n-1).  

.345/180 as a fraction

Multiply both top & bottom by 1000

345/180000

Then divide both top & bottom by 15 and you get

23/12000 which is your answer.

And as decimal fraction=.00191666666...........etc.
