Where have you been Hayley,  we miss you    

Happy belated  Birthday Lance,  I am  sorry that I forgot you on your day.   

I hope you had a really top day      

Trust me, I need halp wayyyy mor than u....

It is times, not add, not subtract, not divide. 

8/40=1/5 

1/5*100%

100%=1

1/5*1=1/5.

Solve for x:
4 x^2 = 90

Divide both sides by 4:
x^2 = 45/2

Take the square root of both sides:
Answer: | x = 3 sqrt(5/2)                  or x = -3 sqrt(5/2)

Lol! I hate video games...

use the carrot symbol ^

What can u multiply to get -12 and add to get 19

This a binomial probaility is given by:

C(7,3) * (.5)^3 * (.5)^4  = 35/128   = about 27.3%

I am going to relax for a bit, alright?

Let's call the seats A,B,C,D,E,F,G

Then, the possibilities  for the chair positions for the three people are :

A C E       B D F       C E G

A C F       B D G

A D F       B E G

And each of the three people can be assigned to these seats in 3! ways = 6 ways

And the other 4 people can be arranged in 4! ways  = 24 ways for each arrangement above

So we have

7 position possibilities * 6 arrrangements of the three people for each position possibility* 24 arrangements of the other 4 people   = 1008 ways

As Melody often says....."That's what I think"

It is -6, but it is because -3*-2=6 and 6*-1=-6

Guest, is it -6x+4 or 6x+4?

In multiplication, you don't add the factors. You see how many times you add a certain number. -3*-1=3 

When 1 is involved, the answer is whatever number you multiply by 1. So now we will do 3*-1. 3*-1=-3

-3 is the final answer.

-6x+4=2(3x-5) first u distribute 2 into 3x & -5.to get 6x-10.then u take-6x+4 & subtract the 4 on both sides.thats what i know

Figured out that this is more relaxing than playing a CERTAIN VIDEO GAME *cough* Ori and the Blind Forest *cough* so I came back. :D

6x+4=2(3x-5)

Distributive Property: 6x+4=6x-10

Subtract 6x from both sides.

4 does not equal -10, so the problem is literally impossible to answer. x has no solution.

\(({\frac{2}{3}})^{-3}\)

\(\frac{1}{({\frac{2}{3})}^{3}}\)

\(\frac{1}{\frac{8}{27}}\)

\(\frac{\frac{27}{8}}{1}\)

\(\frac{27}{8}\)

Hit the "ncr"  buttton at the lower left on the calculator....then type in 15,2   and hit   =

Right! Totally forgot! Thanks Melody!

You did do good rarinstraw1195 BUT  

h could also equal -11

\(h^2=121\\ h=\pm\sqrt{121}\\ h=\pm \;11\)

If it equals window, the problem should be 1+1=?

First of all, let's get y on one side and x on the other.

So, start by adding 2y to both sides. Now you have 3x=2y+6.

Now, subtract 6 from both sides. You now have 3x-6=2y.

Then, divide by 2 on both sides. You now have 1.5x-3=y

The slope in y=mx+b is the number in spot m.  The number in spot m is 1.5, so the slope is 1.5 .
