685,000,000 would be the right number. Hope this helps!

Step-by-step explanation:
Distribute the 5 into the parentheses (multiply them both by 5)

Subtract the 6.5 from -25.

Divide -31.5 by 15.5.

f + 6 = ?
Well, the answer can be pretty much any number. It all depends on what number f is. f is a variable, so you can plug in any number to replace f.
For example, if f was 5, this is what the equation would look like:
5 + 6 = 11
If f was -3, this is what the equation would look like:
-3 + 6 = 3
So, again, the answer can be anything. It depends on what f is.
