Answer 1

`x=28-5.2-12.9`, 9.9 ounces of water remaining.

Explanation:

Given:

Dylan drank 5.2 ounces of water before soccer practice, and 12.9 ounces after practice.

Before he drank any water, there were 28 ounces of water in the container.

Question asked:

Which expression can be used to find the amount of water remaining?

Solution:

Let
`x` the amount of water remaining.

Total quantity of water in the container = 28 ounces

Before practice, Dylan drank = 5.2 ounces

After practice, Dylan drank = 12.9 ounces

Remaining amount of water = Total quantity of water in the container - Amount of water is drunk before practice - Amount of water is drunk before practice

`x=28-5.2-12.9\\ \\ x=28-18.1\\ \\ x=9.9\ ounces`

Thus, 9.9 ounces of water remaining in the container.
