Step-by-step explanation:
This question doesn’t make sense, double check you wrote it right
So for the dice to be 9 two die must be rolled. So we start with a 1/2 chance.
Then there are 36 possibilities to be rolled on a die (6*6) and there are 4/36 possibilities for the dice to roll a 9 (4+5, 5+4, 3+6, 6+3).
So we multiply 1/2 by 1/9 (4/36)- which equals 1/18.
So there is a 1/18 chance for the result of the dice rolled to be a 9.
I hope this helps!
Eliminate one of the variables..
2x + 2y = 28
2x = -2y + 28
8x - 2y= 22
8x = 2y + 22
x = 0.25y + 2.75
combine equations...
-y +14 = 0.25y + 2.75
solve for the variable..
-y - 0.25y = 2.75 - 14
-1.25y = -11.25
y = 9
replace y with 9 in previous equation..
x = -y + 14
x = -9 + 14
x = 5
so y = 9 and x = 5
I hope I did that right good luck!
