Best ResponseYou've already chosen the best response.2@milli_lovesyouu begin by dividing both sides by p.

Best ResponseYou've already chosen the best response.2Very good. Now 3 + nr isn't being multiplied by anything anymore so the parentheses are no longer needed. You can remove them.

Best ResponseYou've already chosen the best response.0okay so then i have to get rid of the n right?

Hero

Best ResponseYou've already chosen the best response.2The next step after removing the parentheses is to subtract 3 from both sides.

Best ResponseYou've already chosen the best response.2The right side is correct, but the left side is incorrect. You wrote 3 as multiplying d/p, but what you actually what to do is subtract 3 from d/p. Have an idea of how to write that?

Best ResponseYou've already chosen the best response.2Very good. How do you write d/p minus three?

Hero

Best ResponseYou've already chosen the best response.2Yes, correct. Subtracting 3 from d/p means the same as d/p minus three. You should pay very close attention to the way math phrases are worded. Now the last step is important and I want you to get it right. First I want you to place everything on the left side in parentheses.

Best ResponseYou've already chosen the best response.0no idea im sorry i tried on paper but it didnt make sense to me

Best ResponseYou've already chosen the best response.2Type it first in here. I'll explain it later. Just simply place the expression on the left side within a set of parentheses.

Best ResponseYou've already chosen the best response.0d/p is outside the ( ) right ?

Best ResponseYou've already chosen the best response.2The entire expression on the left side, put parentheses around it.

Best ResponseYou've already chosen the best response.0(d/p  3) = nr then, multiple both sides by n?

Hero

Best ResponseYou've already chosen the best response.2The expression above is correct as written. Notice that n is being multiplied by r. So to undo that, we have to actually perform an inverse operation. DIVISION. Divide both sides by n.

Best ResponseYou've already chosen the best response.2The final expression is going to look kind of awkward, I know, but no one says the equations have to look pretty.

Hero

Best ResponseYou've already chosen the best response.2You're changing it to something else. When you put the expression in parentheses, YOU CANNOT alter it. It's ONE expression. You divide the entire expression by n.

Best ResponseYou've already chosen the best response.0okay, so it'll be (d/p  3) / n = r ?

Hero

Best ResponseYou've already chosen the best response.2And if you're confused about how that looks on paper, it will look like this: \(\dfrac{\dfrac{d}{p}  3}{n} = r\)

Best ResponseYou've already chosen the best response.2It's unfortunate that they have done that, because now they basically want you to rewrite it in a different form.

Best ResponseYou've already chosen the best response.2No wonder you were confused about how to write the final form.

Best ResponseYou've already chosen the best response.0yea i was looking at my book and other examples but i couldn't figure it out for nothing

Hero

Best ResponseYou've already chosen the best response.2It will be more difficult to explain based on the manipulation necessary to rewrite it in the proper form.

Best ResponseYou've already chosen the best response.0what other way can i write this?

Best ResponseYou've already chosen the best response.0i was looking at answer choice a at first

Hero

Best ResponseYou've already chosen the best response.2The next step is to first rewrite it this way: \(\dfrac{1}{n}\left(\dfrac{d}{p}  3\right) = r\) Believe it or not, the expression on the left is equivalent to the expression we got for our initial answer.

Hero

Best ResponseYou've already chosen the best response.2Next, you distribute \(\dfrac{1}{n}\) over \(\dfrac{d}{p}  3\) to get \(\dfrac{d}{pn}  \dfrac{3}{n}\)

Hero

Best ResponseYou've already chosen the best response.2Afterwards multiply \(\dfrac{3}{n}\) by \(\dfrac{p}{p}\) to get \(\dfrac{3p}{p}\) So the expression on the left now looks like \(\dfrac{d}{pn}  \dfrac{3p}{pn}\

Hero

Best ResponseYou've already chosen the best response.2Notice the denominators are the same so we can combine the expression to get: \(\dfrac{d  3p}{pn} = r\)

Best ResponseYou've already chosen the best response.2A is correct but the important thing to know is how to get A. You can't get it by eyeballing it and you should never try to guess with problems like these.
