-4(x+2y)=      just distribute the -4 over the terms in the parentheses on the left side

-4x - 8y

And that's it.....!!!!!

a% of n= $${\frac{{\mathtt{a}}{\mathtt{\,\times\,}}{\mathtt{n}}}{{\mathtt{100}}}}$$

So 35% of 100=$${\frac{{\mathtt{35}}{\mathtt{\,\times\,}}{\mathtt{100}}}{{\mathtt{100}}}} = {\mathtt{35}}$$

ahhh

i did not know that lol

Thanks bro!

Hi Heather,

It depends on how the work is used.

If you were talking about "a guy" (singular) then you definitely mean a man or at least a male.

But if you talk about the guys (plural) then you may mean men OR you may mean a mixed gender group.  The meaning would be taken from the context.

For instance, if I wanted my mixed gender group of friends to hurry up, I might say

"Come on guys or we will be late!"

Thanks. :) 

youre welcome, my queen

In that case the decision is yours to make!

.

OKay. Thanks. :) But we weren't asked to provide a certain decimal places. 

Omg i did not know that in australia guys meant both males and females

Yes.  It depends on how many decimal places you have been asked to provide.  5.357% is very slightly more accurate.

So is the answer going to be 5.357% or 5.36%?? 

35% of 100 = 35

Thanks Mathcad. I get the idea now.

To three decimal places it is 5.357%

However, to two decimal places it is 5.36%, because the third digit is greater than 5, so you round up the second digit.

(Don't forget to put the percent sign).

NB: It would have been better to add your response to the same thread as your original question (which could have been done by selecting Post answer there).

.

Then the length of 26 of them will be 26 times more than the length of one of them; but since you don't give the length of one of them it's difficult to be more specific!

.

I don't know the terms in English, but google translate said its package. I don't know really how to say it in English.

percent change is given by 100*(final value - initial value)/initial value, so:

100*(590 - 560)/560

You can crunch the numbers.

What is Colis?

Please help me with this? :)

Correct numerical answer Bro, though it would be nice to see your full expressions for x and y!  The reason for this is that there are several ways to solve this problem, each of which can result in expressions that look different, but are, of course, equivalent.
