I know this ...... it is false
She would get £2.50
4 times 2 is 8
2 times 3 is 6
0.7 times 5 is 3.5
Add them together
Minus it from 20
It equals £2.50
Hi, you've asked an incomplete question. However, I inferred you need a brief explanation about The Collatz conjecture.
<u>Explanation:</u>
Put simply, what the Collatz conjecture unsolved problem entails is that if any positive number is picked and it is:
- An even number (eg 2, 4, 6,...), then if they are divided by 2, the new number gotten should undergo the same process (that is to be divided by 2), it is believed your calculation would finally end up at 1. For example, let's pick the number 6, (6÷2=4; repeating the process 4÷2=<u>1</u>)
- An odd number, then if they are multiplied by 3 and 1 is added to the result, it is believed that your calculation would finally end up at 1.
Factors of -48 that add up to 2
-6 and 8
So these are the factors (x + 8)(x - 6)
If you have any of those as th option, it is the answer.
