Here. Sorry for any inconveniences.

Just post off-topic or else the toxic swamp monster will get you.

Oof, toxic swamp monster is here

Here. I did some. Please tell me if I am wrong.

Ok. Thank you.

Jerry's age = x

Brother's age = 1/2x

Sister's age = x -6

y = number of years

x+y = 2/3 (1/2x +y  +  x-6 +y)

x+y = x + 4/3 y -4

y = 4/3 y - 4

-1/3 y = -4

y = 12 years from now

(2x-y) / (x+y) = 2/3

6x-3y = 2x + 2y

4x = 5y

x/y = 5/4

Bro, next time remember to make this a off-topic question cuz its not related  to math.

we know that 10 3-dollars will worth 30 dollars, so items that cost 3 dollars have to be less than ten. 

We also know that 10 30-cents will worth 3 dollars, so the number of cents has to come in 10s since the final cost is 30 which is a whole number.

There will be a lot of cents, so I will just say that there are 20 30-cents, which will cost 6 dollars. If I add 6 2-dollars, then I will get 12 dollars. 12 +6=18. 30-18=12. and 12/3=4. 

4 items cost $3

6 items cost $2

20 items cost 30 cents

A convex octagon has interior angles that add to (8 - 2)(180) = 1080 degrees

If there is one right angle, the remaining angles must average (1080-90) / 7 ≈ 141.4 degrees

If there are two right angles, the remaining angles must average (1080 - 180) / 6 = 150 degrees

If there are three right angles, the remaining angles must average (1080 - 270) / 5 = 162 degrees

If there are four right angles, the remaining angles must average (1080 - 360) / 4 = 180 degrees, but this isn't possible while remaining convex.

So the largest possible number of right angles is three.

(Thank you for helping me with the other math problems I posted earlier... )

I think the answer is... not b, or a... c likely.

x = 3.

2. The answer is 2/399.

3. The answer is 13/33.

1. 13

2. a=-1/7

You are welcome :)

Thank you, that really does help. 

Yes that is right and if you want to use formula (which shouls also be your second choice with these.)

It will be P(3,3) becasue you are only worrying aobut ordering 3 subjects.

BUT

please understand the logic of these without the forumula.

Then when you do need to use it the formula will make more sense.

I apologize, I thought we were supposed to be using the permutation and combination formulas on all of it which is why I got confused. I guess since math would be at 11 you would only have to figure out how many schedules were possible for the other three subjects. Therefore, you would multiply 3,2, and 1 in order to get 6.
