Ok so 6x - 3y = -21
And 4x = 3y - 9
From the second equation, 4x - 3y = -9
So if you subtract the second from the first,
(6x-3y) - (4x-3y) = -21 - (-9)
So 2x = -12
x = -6
Now we know x=-6, and you can sub it back into any equation:
6(-6) -3y = -21
-36 - 3y = -21
-3y = 15
y = -5
So x=-6 and y=-5
Hope this helps
1. Let a: rolling an even number, b: rolling an odd prime number
2. a={2, 4, 6, 8, 10, 12, 14, 16}, b={3, 5, 7, 11, 13}
3. So n(a)=8, n(b)=5 , n(Sample Space)=n(S)=16
4. Since a and b are mutually exclusive events, that means they have no common elements, P(a or b)=P(a)+P(b)=
Ok well if you have 8 students and 2 boards divide the students by 2.
8/2=4
now, if each student wanted to paint part of a board and there are four students then divide 1 by 4
1/4=.25 or 1/4
so 4 students can paint one board while the other 4 students pain the other board
Answer:
Step-by-step explanation:
If you are talking about a die with 6 faces, then 16 isn't possible. 12 is the highest possible number.
If you are talking about some other kind of die, you have to specify it.
I'm going to assume you made a mistake and meant 6.
There are 5 ways to get six
3 - 3
4 - 2
2 - 4
5 - 1
1 - 5
There are 36 ways of throwing 2 dice.
So the probability = 5/36 = 0.1389
If you really did mean 16 then the probability = 0
Ok I got 190,208
I hope this helps
