Answer:
12a + 24 = 6(2a + 4)
Step-by-step explanation:
Given the numbers :
4, 12a 6 2a and 24 ; create an equivalent expression :
12a, 2a, 4, 6, 24
We could separate tbe constant terms and those with variables :
12a, 2a ; 6, 4, 24
We could put the larger digit to one side
12a + 24 = 6(2a + 4)
This way the Right hand side is equal to the left hand side.
Check:
12a + 24 = 6(2a + 4)
12a + 24 = 12a + 24
Hence, the proof
We want to find the probability of getting a red ball in our first draw, given that in the second draw we got a white ball.
We will get P = 0.345
We know that the bowl has:
- 5 white balls
- 10 red balls
- 15 blue balls.
For a total of 30 balls.
We draw a ball and we store it.
Then we draw another ball and we see that it is a white ball.
We want to get the probability that the first ball was red.
The only thing we know, is that one of the white balls can be taken out of the sample space, because we can only draw it second if we did not draw it on the first attempt.
Then we can think that we have:
- 4 white balls.
- 10 red balls
- 15 blue balls.
For a total of 29 balls.
Then the probability of getting a red one is just the quotient between the number of red balls and the total number of balls, we will get:
P = 10/29 = 0.345
