-2 + -6

Here, you are adding two negative numbers (this is like losing 2 and then losing another 6, so you have a total loss of 8, which is written as -8).

If you are adding two negative numbers, add the two numbers (ignoring the negative signs) and then put a negative sign in from of your answer.

Since 2 + 6 = 8, -2 + -6 = -8.

acosh(200/a)  =  30

--->   200/a  =  cosh(30)

--->   200  =  a · cosh(30)

--->   a  =  200 / cosh(30)

--->   a  =  3.74 x 10^-11  (approximately)

Thanks So Much Geno

-√(128)  =  -√(64) · √(2)  =  -8 · √2  =  -8√2

3 - +2 means to subtract a positive 2 from a positive 3 (positive numbers don't need a positive sign in front of them, so 3 = + 3 and +2 = 2):

=  3 - 2

=  1

To reduce by 80% means to save 20%:

20% of 1/1000  =  0.0002  =  2/10 000  =  1/5000

Student's t cumulative distribution function:  this evaluates to 0.887

(using a TI-83+ calculator).

2(5 - 2m)  =  -6(3m - 2)

Multiply out by using the distributive property:

10 - 4m  =  -18m + 12

Add  18m  to both sides:

10 + 14m  =  12

Subtract  10  from both sides:

14m  =  2

Divide both sides by  14:

m  =  1/7

dang, this evil orginization sure likes to challenge math masters, im starting to suspect here that whoever started this Anti-Forum Orginization is actually one of the mods trying to take over the forums...

it could be melody!

it could be CPhill or CPhill II!

It could be alan!

maybe radix!

or maybe it can be some of the social people

it could be Rosala

it could be brittany

it could be my main ego, TR

or, it maybe could even be you anonymous!

it maybe could be even zegroes whos been staying silent

anyways, lets get this problem over with

according to a math master here,

1 year=31,536,000 seconds

1 trillion seconds=1,000,000,000,000

so, 1 trillion seconds=31709.7919837645865043 years, scratch that off, the approximate amount is 31, 710 years

$${\frac{{\mathtt{1\,000\,000\,000\,000}}}{{\mathtt{31\,536\,000}}}} = {\mathtt{31\,709.791\: \!983\: \!764\: \!586\: \!504\: \!3}}$$

so, overall, the teacher on the radio is definetely correct, it will take about 31, 710 years to reach 1,000,000,000,000 seconds

anyways, whats the emergency? did capt. man pop another kids birthday balloon on "accident"?

oh, i see the emergency, looks like my main ego is at a ambush. no worries, i got this

*blows up main ego's trojan horses

*breaks into castle, shoots the first 20 royal soldiers inside

*shoots rapidly with a machine gun (a "secret" weapon i carry)

*reaches the top

*takes out sword, fights main ego

*jumps off building while shooting at main ego, stops the ambush

*throws some dynamite, building explodes

*cia comes in to take care of the scene, tr escapes, but more poor than ever

there, emergency taken care of

$${\frac{{\mathtt{3\,229}}}{{\mathtt{7\,939}}}} = {\mathtt{0.406\: \!726\: \!287\: \!945\: \!585\: \!1}}$$

most accurately 3229: 40.67262879455851%

most approximae answer: 41%

no monkey business. the name's Titanium.

alright, no monkey business, this is a serious fraction orginization trying to go rogue and betray the Forum's Orginization.

alright first step: make the fractions equlvalent

starting problem:

1 2/3+2 3/4

since denomenators 3 and 4 arent related, or equivalent,we will have to multiply them both

2/3*4/4=8/12

3/4*3/3=9/12

8/12+9/12=17/12=1 5/12

and we will add the whole numbers, 1+2=3

3+ 1 5/12= 4 5/12

overall, 1 2/3 + 2 3/4=4 5/12

now lets get out of here, this fraction base is about to be blown up by my main ego

Hi     TR or is that RT

Isn't one of you enough. LOL

hello, this is Royal Titanium aka TitaniumRome's second and alternative ego.

things you should know about Royal Titanium:

-super smart

-does not focus on taking over the world

-instead is a CIA UnderCover Agent that tracks down evil orginizations just like Tom Cruise and James Bond

-shows less mercy than TitaniumRome to the enemy

-more serious during cases

-less serious when joking around

-does not rely on troops, does the job himself and with other agents, or friends

-can defeat captainman without the needs of a gun or jolly beetle spray potion

-never goes back in time

-always wears sunglasses

-faster than titanium rome

-does stunt moves rather than using spells or artilery, uses explosives instead

-weapons of choice:

*Desert Eagle

*Dynamite

*any kind of sniper gun

*Revolver (that killed lincoln)

-recognization suit:

-agent suit:

*black jeans, black running shoes, very dark gray t-shirt, black coat, sunglasses

-undercover suit:

******** (can never be revealed)

catchphrase: There Are No Rules In My World

aliases under this ego:

-Royal Titanium (main alias)

-Agent Royal (agent alias)

-****** (undercover alias)

id code: ***-***-*** (can never be revealed)

-gadgets:

*titanium armor (almost everywhere)

*dynamite

*Shock Tasers

*matches!

*jetpack

Great answers.  Thanks Chris and Heureke.

I especially like yours Heureka. 

I also like that Latex stacked question mark.

That'll have to find its way to the latex thread :)  I have added it  now :)

Thanks anon

Yes that is correct :)

This is actually very simple. Square root of 49=7 and square root of 81=9

Soo...

7/9

(i think)

4+x=26

To solve this, we want x on one side with no other terms.

So, we need to get rid of the four on the left side.

However, in an equation, you can't just eliminate a term completely without doing the same to the other side.

Since 4+(-4)=0, we can add -4 to each side.

4+x=26

4+x+(-4)=26+(-4)

Now, we simplify by adding like terms (terms that are the same with different coefficients).

x=22

So that would be your answer, 22=x.

Knowing how to do these problems is the base of Algebra. I suggest strengthening this concept with math tools such as Hands-On-Equations which is fun and explores Algebraic Thinking.

 Hope this helped.

Thats how i solved it(according to your recommendation to solve the top and bottom separately:

first of all:a≠2,3

x²-4x+4>0                              x²-4x+4<0

and                      or                and 

x-3>0                                      x-3<0

    ⇓   numenator:x²-4x+4=0          ⇓

                       (x-2)²=0

                         x=2

x ≠2                                         no x

x-3>0           denominator:

x>3                                           x<3

 so the answer:x>3

OK, lets do some multiplication and sort this out.

Days in a year* Hours in a day* Minutes in an hour* Seconds in a minute= YOUR ANSWER

I am not entirely sure what you are asking for, but I tried to kind of solve these for you.

1. Equal or 25=25

2. Equal or 18=18

3. -17<10

Your answer would be 23/1000000

Just count the places until you reach the end of a decimal and then put that amount of 0s behind a 1.

It's actually a very simple concept that I recommend you learn as it will be essential in later mathematics courses.

CPhill a question.

You set x= 3 and that makes the fraction divided by zero.  I thougt that was not allowed for solving equations. Is it because it is ploted on the the graph and the line dissapears or goes to infinity when x=3 that it is allowed?

4+x=24

-4     -4

x=22
