Answer 1

First substitute p = 2.75 for every p in the expression.

- 13.75 ÷ p + 2p becomes 13.75 ÷ 2.75 + 2(2.75).

Then evaluate each operation (division and multiplication) before adding:

- 13.75 ÷ 2.75 = 5
- 2(2.75) = 5.5

Finally add the results:

- 5 + 5.5 = 10.5

So the value of the expression when p = 2.75 is 10.5.
