Determine the probability of drawing red and green without replacement
This is calculated as follows:
We used Total - 1 because it's a probability without replacement:
<em>Hence, the required probability is 1/11</em>
The correct answer is the correct spelling correct answer is that I don’t answer my question about it is correct
Answer:
x= 5.25
Step-by-step explanation:
You have to get x alone, so do inverse operations.
(Basically, reverse what it is)
4(x-3)=9
divide 4 by both sides to get rid of 4 on left side
9/4 = 2.25
(x-3) = 2.25
Now add 3 to both sides, to get x alone
2.25 + 3 = 5.25
x=5.25
Check work
4(5.25-3) = 9
4(2.25) = 9
9=9
Answer:
11 ; 13
Step-by-step explanation:
Let the numbers be :
x and x + 2
x * (x + 2) = 6(x + x + 2) - 1
x² + 2x = 6(2x + 2) - 1
x² + 2x = 12x + 12 - 1
x² + 2x = 12x + 11
x² + 2x - 12x - 11 = 0
x² - 10x + 11 = 0
x² - 11x + x + 11 = 0
x(x - 11) + 1(x - 11) = 0
(x - 11) = 0 or (x + 1) = 0
x = 11 or x = - 1
X cannot be negative
x = 11
x + 2 = 11 +2 = 13
Let cost of 1 apple i=x dollar
and cost of 1 orange =y dollar
according to question we get following equation
james, 5x +10y=4.......(1)
donald, 3x+9y=3........(2)
solving 1,2 eq. we get
x=2/5 dollars and y=1/5 dollars
