Answer:
x = 3 and y = 2
or
(3,2)
Step-by-step explanation:
first equation (LCM = 3 x 4 x 5 = 60)
(x+2)/5 - (9-x)/3 = (y - 6)/4
12(x+2) - 20(9-x) = 15(y - 6)
12x + 24 - 180 + 20x = 15y - 90
32x - 15y = -90 - 24 + 180
32x - 15y = 66
second equation:
8(x + 2) - (2x + y) = 2(x + 13)
8x + 16 - 2x - y = 2x + 26
6x - y + 16 = 2x + 26
4x - y = 10
Now you have 2 equations:
4x - y = 10 ---> y = 4x - 10
32x - 15y = 66
Substitute y = 4x - 10 into 32x - 15y = 66
32x - 15(4x - 10) = 66
32x - 60x + 150 = 66
-28x = -84
x = 3
y = 4(3) - 10
y = 12 - 10
y = 2
Solutions: x = 3 and y = 2

Answer:
1/36 ≈ 0.028
Step-by-step explanation:
In order to get a total of 2 if you roll 2 dice, you have to roll two ones. (You can't roll a 0 and 2 because an average die does not have a zero on it)
You have a 1/6 chance to roll a 1 on the first die; and you have a 1/6 chance to roll a one on the second die.
To find the probability of this happening together you have to multiply them together.
1/6 * 1/6 = 1/36 = 0.0277778 ≈ 0.028
