is this what you meant 6-2*6-2x=6x-10x+86x-10x+8

then the answer goes like this-

24-8=6x-20x+86x+2x

16=64x

x=1/4

Give it a go Coldplay and I will tell you whether or not you got it right,

Then i can teach 2 of you at once :)

Hint:  Be careful with the minus sign.

think of it like this

5a+3b        +       -4(2a-5)     -8a

No 

0^0 is undefined    

Hi Katieleigh,

This is how I think of problems like this one

what persent of 860 is 43? don't give me the answer though I just want the formula

First I think "What FRACTION of 860 is 43?"        Well that would be    43/860

THEN      How do I change a fraction into a percentage?   Well I multiply it by 100 of course!        43/860 *100 %

You lot are really funny   

Thanks for coming to the rescue Alan :)

Is Coldplay and Victoria the same person  ????

You kids do my head in    

It is 4, if u can actually post this question, then how do you not know what 2+2 is?

Big hint for younger members and guests:

Kurt can buy one pound of nails for $3.55. How many pounds of nails can Kurt buy for $12? Round to the nearest hundredth.

Many of you are really confused as to whether you should multiply or divide or perhaps do something else.

The BEST way to  deal with this dilemma is to substitute easy numbers for the hard ones and see what you would do.

SO I might change  this question to

Kurt can buy one pound of nails for $6   many pounds of nails can Kurt buy for $12? Round to the nearest hundredth.

Well now the answer is pretty obvious it is 2 ofcourse because 2*6=12

BUT 

how can we put 6 and 12 together to get 2.

well 12  ÷ 6 = 2      So it is division!!!

12  ÷ 3.55 will be the answer!

12/3.55 = 3.3802816901408451

So he can buy 3.38 pounds of nails!      

0.2²=0.2×0.2=0.04

Numbers help to simply explain the universe 

Me too, thanks

For Coldplay 

"Sorry, I read the problem wrong! Now I sound like Nauseated defending myself.:)"

You better hope that Nauseated finds this as funny as I do.  ROF LOL    

I'm breaking up here   .........

Coldplay is great is s/he not Nauseated.    

I understood what you wrote Alan, 

but the book answer confusses me, 

why did he put the kinatic energy of the ramp in the equation of conservation of energy ?! 

it suppose to be for the box ! 

(55*32)X=313

X= 313/(55*32)

313/(55*32) = 0.1778409090909091

Great work Chris,

This looks interesting and involved.  I will have to see if i can find time to try it for myself.

Arrrr too many toys to play with - never enough time - many are not done justice - what are great sadness.  

I think 2 would be not the same as 1 so, infinite I guess...

 If that is what you meant, I hav never heard of that before.

Is it? If so, im not sure why...

Write the slope-intercept form of the equation of the line described.

A line through (-4,0) Perpendicular to y=x-1

The slope-intercept form of a line is y = mx + b, where m represents the slope and b represents the y-intercept.

The equation y=x-1 shows that the slope of the line m is 1.

The line perpendicular has the slope \(m_{\text{perpendicular}} = -\frac{1} {m} = -\frac{1}{1} = -1\)

The line through (-4,0) is  \(0 = (-1)\cdot (-4)+b\)

so  \(b=-4\)

The slope-intercept form of the equation of the line is  \(\mathbf{y = -x - 4}\)

Last​ year, a​ college's tuition was ​$42,500 . This​ year, the tuition increased by​ 4%. Find this​ year's tuition by using a percent greater than 100

Last year's college tuition=$42,500

This year's tuition: 104% X $42,500=$44,200.

I'm getting tired of waiting for someone to answer, tell me if correct.

               12*62\9=

744/9=248/3=82.6666666666666667

What grade are you in? I don't understand your math, I hav an idea but it'll probably be wrong.

 I can't help, but good luck! You should make an account if you have an account your questions (according to Melody) are made top priority.:)

0.7%   =  .007

So

62000 *  .007   =  434  acres

65% =  65/100   = 13/20      ....so we have

(13/20) * x   = 260       multiply both sides by 20/13

x  = 260 (20 / 13)  =   (260 / 13) * (20)  =  (20) * (20)   = 400

12h=4(2h-5)    simplify

12h  = 8h  - 20    subtract 8h from both sides

4h  =  -20       divide both sides by 4

h = -5
