- Meehan98

If x and y both equal 3, you substitute 3 for x and y in the equation.
\[\frac{ 4(3)-(3) }{ 2(3)+(3) }\]

@TypnoEchosis try it you can do it, it is not that hard :)

- anonymous

it is if you have problem learning :)

- pinklion23

@Meehan98 that is what i just demonstrated

- pinklion23

well i can not do it for you that would be braking the code and you where like this last year i know you can do it ;)

- Meehan98

Yea, it was taking me awhile to type it out...

- pinklion23

ok

- pinklion23

look @TypnoEchosis i put in the numbers for you take my drawing and finish the equation as best as you can then we will go from there

- anonymous

Yeah the problems is this is the third time I did this and I did the whole equation thing and still got it wrong and it was the right way too. Sorry but math is my weakest subject and will always be ^.^

- pinklion23

Won't the 2*3 be 6???

- Meehan98

Yes, the 2*3=6 So, now you know that, what is your answer?

- anonymous

I got a really long number o.O is there something i'm not doing right

- Meehan98

What is 12-3?
What is 6+3?

- anonymous

9 and 9

- Meehan98

So, \[\frac{ 12-3 }{ 6+3 }\]
would be.....

- anonymous

1 :O

- Meehan98

Yep!!!

- anonymous

Yay :D can you help with 2 more that is if you can

- Meehan98

I can try!

Is this pre-algebra you're working on?

- anonymous

it's like 9th grade stuff but i'm homeschooled it's very different

- anonymous

should we just continue here or what xD

- Meehan98

I see! It doesn't make any difference to me.

|dw:1441824182565:dw|

- Meehan98

Okay, so if you know that 18 is the base and 11 is the height, just fill in 18 as "b" and 11 as "h". Now, what does your formula look like?

- anonymous

|dw:1441824493478:dw|

- pinklion23

sorry computer crashed

- anonymous

Oh that's okay

- Meehan98

Great! So, now you multiply (11) * (18) and your answer from that will be divided by 2 because you're taking 1/2 of it. What answer do you get?

- pinklion23

i guess im not needed good job meehan98 :/

- anonymous

99?

- Meehan98

Haha! Thanks:)

- Meehan98

Yes, that's correct!

- anonymous

Yay

- anonymous

just one more than i can go free :D

- Meehan98

Okay, I hope you're understanding how to do it a little more!

- anonymous

the expression 2l + 2w is used to find the perimeter of a rectangle with l and w
what is the perimeter if l= 14cm and w= 4cm

- anonymous

and yes i'm understanding a little bit more :D

- Meehan98

What do you think will be the first step?
