Answer:

8a + 2b is 14 and b - 2a is 4 1/2

Step-by-step explanation:

divide 8 by 2 to get 4 and multiply 2 times 5 to get 10, then add 10 + 4

If b=5 and a is 1/2 then 5 - 1/2 = 4 1/2

Answer:

There are 3478761 ways to select the first 5 numbers

Step-by-step explanation:

As understood from the statement of this problem we assume that it does not matter the order in which the first 5 white balls are selected.

In this case it is a combination.

So, what we want to know is how many ways you can choose 5 white balls out of 55.

Then we use the formula of combinations:

C(n, x) = \frac{n!}{x! (n-x)!}

Where you have n elements and choose x from them.

Then we look for:

C(55, 5) = \frac{55!}{5!(55-5)!}\\\\C(55, 5) = \frac{55!}{5!(50)!}\\\\C(55, 5) = 3478761
