27 i believe
you would substitute y with 0 to find x then you would put 9 in for x to find y then you would go back to the first equation and put -19 in for y and then solve for x and get 27
8 X
----- = ------
20 40000
40000/20=2000
2000*8=16000
X=16000

Answer:
Step-by-step explanation:
x + y + z = 1
-x + 9y - 3z = -49
10y - 2z = -48
2x + 4y + 2z = -6
-2x + 18y - 6z= -98
22y - 4z = -104
-20y + 4z = 96
2y = -8
y = -4
10(-4) - 2z = -48
-40 - 2z = -48
-2z = -8
z = 4
x - 4 + 4 = 1
x = 1
x = 1, y = -4, z = 4
Answer:
Step-by-step explanation:
You would add probabilities if you want to find out if one event or another could happen. For example, if you roll a die, and you wanted to know the probability of rolling a 1 or a 6, then you would add the probabilities:
Probability of rolling a 1: 1/6
Probability of rolling a 6: 1/6
So the probability of rolling a 1 or a 6 is 1/6 + 1/6 = 2/6 = 1/3.
