Pip was thinking of a number. Pip doubles it, then adds 6 to get an answer of 13.8. What was the original number?

The original number is 3.9.

Step-by-step explanation:

With the information given, you can write an expression where the number multiplied for 2 plus 6 is equal to 13.8:

2x+6=13.8, where x is the original number

Now, you can solve for x to find the original number:

2x=13.8-6

x=7.8/2

x=3.9

According to this, the answer is that the original number is 3.9.
