Thank you for your help, on a side note, do any of you have a good site that you could recommend where I could learn for myself how to do problems I have trouble with, that being said I'm glad I cam across this site since it has been help.

Also I don't slack all the time, just sometimes.

Thank you for acknowledging our efforts.

There are lots of good sites. When we are helping people we often go looking ourselves and supply web addresses to people.
mathsisfun is a site that we refer people to very often. It has lots of great units.
purplemaths is another that I think i have seen people be referred to - although I am less familiar with it myself.
There are a lot of good youtube clips that cover a multitude of topics. I often use them for my own learning.

Also,
If you use this site and you want a particular type of help just state that in your question.
Like you could have said " I need to find the area of a regular octogon..... Please give me a hint on how to get started. I am not looking for the answer yet."

If you join up you will get preferential treatment so then there can be a much faster turn around between responses and we can help you to learn more effectively.
I think you need a more positive username though... like... hardwork=success. Or just your name if you prefer.

how find the sURFACE AREA of a triangle thingy

what is a triangle thingy.
Maybe a triangular prism. That has 2 triangles and 3 rectangles.
Maybe a triangular pyramid. That has 4 triangle sides.

Either way you find the area of each of the sides and add them all together.

cats1251:
:?: If you weighed 32 kg (70 pounds) on Earth, how many kilograms would you wiegh on the neutron star?

That would depend on the mass of athe neutron star. But you would weigh much more.
Mind you, I think that kg is a measure of mass rather than weight and your mass would stay the same.

Gina had a box full of board games she was selling at a garage sale. After she sold 7 board games, there were only 4 left in her box. Which equation shows how to find how many board games,b,Gina had when she started?
Gina started with 11 board games. Just add 7 and 4 together and you get the answer! Not so complicated, right?

what is the area of a 2 by four rectangle

The area of something is how many squares fit inside.
How many squares are there here?
You have to write units squared OR u ² afterwards.

FarrO:
sin(x) = 2/8
cos(x) =?
how to

Draw a right angled triange.
Mark one of the acute angles as x
Put 2 on the opp side adn 8 on the hyp (because sin = opp/hyp)
Use pythagoras theorem to find the adjacent side
read cos(x) off your triangle.

rtgsrtwerte:
-5x+7y=11
-5x+3y=19

The easiest way is to add the 2 together

-5x+-5x+7y+3y = 11+19

10y = 30
y=3

Now substitute y=3 into either of the original equations to find your x value.

SOMEONE:
I hate maths and I'm not good. What can I do for a better performance at the lesson? HELP!!!

What do you want help with exactly. Maybe we could start from there.
The reason that you hate maths is that you do not have much success at it.
It is hard to like something that makes you feel stupid. And it is hard to learn something when you have already decided that you can't do it before you start.
It is a viscious cycle.
If you really want to improve then give me a starting point and we will go from there. It is really up to you.

Guest:
square a number, then take away 5, next multiply it by 4, take away 7, divide it by 3 and add 6 and get an answer of 9.

Let the number be x

[(x ² - 5) x 4 -7]/3 + 6 = 9

Now just solve it.

what i s3.808959826441058e+24 in number form

hi fgh...
you have correctly answered
3.808959826441058e xp+24

Now Woody,
Did you mean what fgh... answered?

OR
Did you mean
3.808959826441058e ²⁴ ?

3.808959826441058e^24=

OR maybe you quite literally meant
24+3.808959826441058e (though I doubt it)

24+3.808959826441058*e=

Hi Betsie,
sqrt(u ¹⁴x16x3)
I factored out 16 because 16 is the largest square number that goes into 48.
=u ⁷*4*sqrt3
=4(sqrt3)*u ⁷

j3ssvern:
a recent Harris Poll survey of 1010 U.S. adults selected at random showed that 627 consider the occupation of firefighter to have a very great prestige. Estimate the probability (to the nearest hundred) that a U.S. adult selected at random thinks the occupation of firefighter has very great prestige

The fraction of adults who think the occupation of firefighter is prestigious is 627/1010

627/1010. This is the same as the probability! However, because you mention "to the nearest hundred" I assume you want the number of adults in the population who think this. As there are roughly 300 million adults (age 18 or over) in the U.S. this means the number is

300*10^6*627/1010
This is 186 237 600 to the nearest 100.

You could ask your teatcher to give some real applications for the subject you are learning. It's easier to understand and memorize, and perhaps starting to enjoy math, since it's a huge tool in many fields. Anyway, I think that different people have different habilities and passions, so they shouldn't be forced to learn a subject they don't like. People should be free to learn what they think it's necessary for their life or work.
