5... you just moved them, you didn't take them away

 

This is the HOMEWORK HELP THREAD not the "get your post count up by posting useless shit!" thread. Thanks for being a dumbfuck. And yes, 5 is obviously the answer...

 

Nevermind/found my answers. thanks for the thread.

 

Yes, and I'm glad that you're banned for your inappropriate outburst.
-Matt, is there any way that you can have those posts deleted?

Still helping people out here for Math Homework.
-And I need some help with mine. If anyone wants to help, please PM me.

 

I need help with my Algebra. We're doing equations like this...-

X-(-2)=12 Find value of X.
-2P-(-5)-2P=13 Find value of P.


If you could show me what steps to take on equations like these that would be great!

 

Here's how you do this:

[X (minus) (-2)] is the same as [X + 2]

So, you have this now:
X + 2 = 12
X = 10

Plug it in: (10) - (-2) = 12
10 + 2 = 12
12=12 (SOLVED!)

Yet again, Subtracting a negative is the same as a positive:

-2P + 5 - 2P = 13

Group:
-4P + 5 = 13

Subtract 5 from both sides:
-4P = 8

Divide:
P = -2

Plug it in:
-2(-2) - (-5) -2(-2) = 13
4 + 5 + 4 = 13
9 + 4 = 13
13 = 13 (SOLVED!)

~~~~~~~~~~~~~~~~~~~~~~

Any more questions, feel free to ask.

 

Yeah we're just getting into converting decimals and regular numbers into percents, and ratios and rates. I could use some help.

At 60 MPH, a car travels 340 miles on 20 gallons of gas.

1. What is the average mileage per gallon of gasoline?
2. How many miles could this car travel on 5 gallons of gasoline at the same speed?
3. What percent of the 20 gallons is 5 gallons?
-----------
Solve the equation.

4. 6(Q + 22) = -120
------------------
Write the equation in standard form with integer coefficients.

5. Y = -3X + 9
6. Y = 1/2X + 4

I need to know how to do the work from step 1 to the end.

 

1) Mileage = Total Distance / Total Fuel Consumed
= 340/20
= 17miles/gallon

2) If a car travels 17 miles on 1 gallon, it will travel 17*5 miles on 5 gallons.
17*5 = 85 miles.

3) 5 is one quarter of 20.
1/4 * 100 = 25%.

4) 6(Q+22)=-120
6Q+6(22)=-120
6Q+132=-120
6Q=-252
Q=-42

Q = - 42.

EDIT: I'm not sure what it means by 5 and 6, although I know what standard form is. 1am over here, sleep time

Please make sure you understand what you're copying down, if there's something you don't get just ask! You won't learn anything otherwise

 

EDIT --> Fat got 1-4 right, but I'll show you another way of doing #4

Here are 4, 5, and 6.

Okay, you can divide both sides by 6; yielding:
[6(Q+22)]/6 = -20
Q+22 = -20
Q = -42.

Plug it back in to the equation;
6(-42 + 22) = 6(-20) = -120. This checks out.

Standard form is Ax + By = C

You need to get all the X's and Y's on one side. To do this, you can just add 3X to both sides;
Y + 3X = 9 - 3X + 3X;
3X + Y = 9.

The coefficients (A=3, B=1) are both integers, so this is the answer.

Again, we need to get X and Y on the same side. We can rewrite 1/2X as 0.5X, so;
Y - 0.5X = 4
Since we need integer coefficients, we can multiply both sides by 2 (to get rid of the X/2) --
2(Y - 0.5X) = 2(4)
2Y - X = 8
-X + 2Y = 8 --> Standard Form with all coefficients being integers.

If you have any further questions, don't hesitate to ask.

 

dangit who is going to help me now?

i just got my math grade to a C for the first time -.-

( im in AP class's for all the rest so gtfo, i just suck at math)

 

Don't worry. I'm still here, and there are also others who would be happy to help you out.

This Thread should stay IMO, for I was still chosen a long while back to be secondary owner of this Thread, to help out others.

Still helping people out. Post your Homework here!

 

Thanks for the help guys. Hey man sorry to hear about Matt. He didn't deserve to be banned like that. We all make mistakes =[


Thanks again.

 

I see a paradox (assuming that AP is a person here)

 

Hmm, was that a joke?

AP = Advanced Placement.

 

I need some help REALLY REALLY REALLY fast!
Here is my problem:
For FRIDAY I have to write an essay!
The problem is that my Microsoft Office TRIAL (Which I just found out was a trial) just closed down. I can't use it anymore. It's expended.
So, I need to get a free-to-download program, like Microsoft Office, where I can write it. I have tryed googling "Microsoft Office Download", but I didn't really get any results.
I need a new program / renewed Microsoft Office ASAP.
What I will do know is trying to illegally download Microsoft Office. O.O
Post some programs.
Thanks you very much in advance!

Problem solved.

 

Thank you very very much, TFC.
You saved my life.

 

I dont really have time now to do these problems , but i will study them [ i can remeber word-definition , so can you guys help me do this for me]

Alright I need some help on my Earth Science homework. I'm stuck on this question and I can't find it in the book.

COMPARE "Earth's compositional layers with its structural layers."
