Answer:
320 - 65 = d
Explanation:
This question looks like it asks for an equation. We don't need to solve it per say but just set it up. If "d" represents the amount of miles we need left we just need to do a simple subtraction equation and instead of "solving it" we just put d as the answer. It'd look something like this:
320 - 65 = d
If you need to solve it, it's just 320 - 65 which would be 255. You don't need to for this question though.
Hope this helps and have a nice day!
