I'll take a CLOSE look at these now because i slept, before i had a high fever.Ok, I'll start off at question 2) 

Ok, I'll start off at question 2) 

5x*6xy? hmm...

5*6=30 

OH!!!(took like 3min ha)

Just realised lol.

There are two  x's being times!

so, 30x^2y   ...i think

Q3)3(x+4)=12x 

so, 3*x=3x and 3*4=12

3x and 12 aren't like terms so the answer is ah, 3x+12, makes a lot of sence when it's looked close at.

Q4) 2(x+4)=

again, 2*x=2x 2*4=8

Not like terms, 2x+8

Q6) 3-4(5x-6)=  Not sure...But I'm taking a hard stare.

I understand it now.Sorry, i had check online, not once in my life have I ever been invited to a question like this I didn't know how to solve it.

Simplifying 3 + -4(5x + -6) = 0 Reorder the terms: 3 + -4(-6 + 5x) = 0 3 + (-6 * -4 + 5x * -4) = 0 3 + (24 + -20x) = 0 Combine like terms: 3 + 24 = 27 27 + -20x = 0



I thought you'd have to times everything by 3 rather than add.

 
(Darn, I can't get out of this text form!)


3x/2 + 4x/5 = 

The reason I did this is because in school, the way i learnt to times fraction is 

Numerator*Numerator
Denominator*Denominator

12x/10
Maybe simplify it

6x/5?


0.06/0.2  
Well I've never divided a decimal by decimal before...Or actually considered it.


so, I'm not sure what my mistake is all i know is that my brother told me a fact, that i nver thought about dividing in decimals will make it smaller, multiplying- bigger...

Honestly, I have no idea....With Google helps.

1. To divide decimal numbers:

   1. If the divisor is not a whole number, move decimal point to right to make it a whole number and move decimal point in dividend the same number of places.
   2. Divide as usual. ...
   3. Put decimal point directly above decimal point in the dividend.
   4. Check your answer.

    

   1. so 0.2 = 2   0.06 = 0.6  

   2.2/0.6=3.333333

   3.so like 33.3

    

   Not sure...Hard to do it on computer but I'm positive It's wrong...

    

   

    

You're so funny Zegroes.

Most people don't speak their mind, but you do!

If i was the background person just reading this I'd probably think this is so cheesy.

But, it actually Isn't, if it was there'd be hugs.

Are you the person who's taking away points from everyone's comment? (I think so )

And stop copying all of James answers.

He is in trouble with the gods.

In percentage, 1=100%

So, 0.5=50%

0.05=5%

Also to convert a decimal to a percentage *100.

0.05*100=5%

0.5*100=50%

So, Zegroes is right.

Thank you!

Someone understands me!

Same responce with my mum, these days i don't ask...

Same here, My mum's way too over=protective i have to get home straight back from school, can't go even to the park with my friends, shops or even having a phone...

Same brother, always checking on me.

Silver Rager! Cool!

Also, sorry for the long response, i was doing Latex in that time (lol), it takes a lot of time to do, but the results are very satisfying.

Also, when you were gone i created a new post called Latex -part 2

$$\begin{array}{rrlll}\\\\
2(x-3)+5x&=&4(x+2)-5\qquad&(2x-3)=2x-6\;and\;4(x+2)=4x+8\\\\
2x-6+5x&=&4x+8-5\qquad&(+5\;on\;both\;sides)\\\\
2x-1+5x&=&4x+8\qquad&(+1\;on\;each\;side)\\\\
2x+5x&=&4x+9\qquad&(-2x\;on\;each\;side)\\\\
5x&=&2x+9\qquad&(-2x\;on\;each\;side)\\\\
3x&=&9\qquad&(Divide\;both\;side\;by\;3)\\\\
\frac{3x}{3}&=&\frac{9}{3}\qquad&(Cancel\;out)\\\\
3&=&x\\\\
x&=&3
\end{array}$$

This is my answer and i swear I haven't looked at Zacs post yet, i care about my education and if i don't make mistakes then i'll make progress, if i get it wrong and don't cheat it's better than cheating and getting it right.

I think i got it wrong at the first step, but then I got a result.

Took me about 15-20min to do. 

Code:

\begin{array}{rrlll}\\\\
2(x-3)+5x&=&4(x+2)-5\qquad&(2x-3)=2x-6\;and\;4(x+2)=4x+8\\\\
2x-6+5x&=&4x+8-5\qquad&(+5\;on\;both\;sides)\\\\
2x-1+5x&=&4x+8\qquad&(+1\;on\;each\;side)\\\\
2x+5x&=&4x+9\qquad&(-2x\;on\;each\;side)\\\\
5x&=&2x+9\qquad&(-2x\;on\;each\;side)\\\\
3x&=&9\qquad&(Divide\;both\;side\;by\;3)\\\\
\frac{3x}{3}&=&\frac{9}{3}\qquad&(Cancel\;out)\\\\
3&=&x\\\\
x&=&3
\end{array}

ok, i thought i had to answer them in latex and workings showed i'll try  them quicker under.

Q2) 5x*6yx=30xy

Q3) 3(x+4)=12x    -      (3*x)+(3*4)=12x

Q4) -2(x+4)=-10x         -       (-2*x)+(-2*4)=-10x

Q5) 17 - 4x -x +5=22+(-5x)        -         (like terms -x & -4x and 17 & +5) 17+5=22   /    -4x-x=-5

Q6)3-4(5x-6)=23x+24           -  (Not sure but...)   (-4*5x)+(-4*-6)=-20x+24        +    (3*5x)+(3*-6)=15x+(-18x)   15x+(-18x)-20x+24=-23x+24

Q7) 3x/2 + 4x/5 = 12x+10

Q8) 0.06*0.3=0.018        (6*3=18/1000=0.018 )

Q9) 0.06/0.2                  (6/2=3/1000=0.003)

Q10) 3x^2 +2x +5= 3x^2+2x+5       (Like terms none) the answer is given

Q11) 5x+2/6y * 9xy^2= ....Have no idea. 

WAIT.  9xy^2 as a fraction...ah
