Answer:
Step-by-step explanation:
--- 1
--- 2
---3
-1 times the second equation = 
= 
--4
Now we are given that replace the third equation by the sum of itself and -1 times the second equation
So, New third equation = 
=
Hence the new third equation is
Answer:
1/76
Step-by-step explanation:
Five marbles are red,
four are green,
ten are blue, and
one is white.
Sample space S= 5+4+10+1= 20
Probability of selecting a red Mable
Pr(red) = 5/20= 1/4
Probability of selecting a white Mable without replacement after the first selection
Pr(white) = 1/19= 1/19
the probability of selecting a red marble and then a white marble without replacement?
= 1/4*1/19= 1/76
You start by writing the equation; x + x - 11 = 35
Then you combine like terms giving 2x - 11 = 35
You solve for x resulting in x = 23
So the numbers would be 23 and 12
