Yes, you can mix Dawn and Roundup together, but it is not recommended for optimal weed control.
Adding Dawn dish soap to a Roundup (glyphosate) mixture acts as a surfactant. It breaks the surface tension of the liquid, allowing the herbicide to spread evenly and stick to the waxy leaves of weeds rather than beading up and rolling off.
Probably not a good idea. Roundup is only slowly taken up through the leaves and is easily washed off. There is a steady trade in surfactants and oils that are supposed to increase its speed of uptake and give better results. Since vinegar is likely to scorch the leaf, IMHO it would slow down the uptake of Roundup.
Roundup Alternatives With Essential Oils
To kill weeds permanently, you need to eliminate the root system while stopping future seeds from germinating. There is no single magic bullet, but combining a targeted post-emergent (to kill existing weeds) with a pre-emergent (to prevent regrowth) delivers the longest-lasting results.
Create a fast-acting, non-toxic weed killer by combining 1 gallon of white vinegar, 1 cup of table salt, and 1 tablespoon of liquid Dawn dish soap. Pour the mixture into a Garden Pump Sprayer and apply directly to weeds on a hot, sunny day.

To make Roundup work better, spray small (2 to 4 inch) actively growing weeds on a sunny day. Additives like ammonium sulfate (AMS) to condition hard water and non-ionic surfactant to help the spray stick can significantly boost the herbicide's effectiveness.
One of the first mistakes that people make is trying to pull up the weeds before they've had time to properly absorb the weed killer. When the weeds have been sprayed, it can take a couple of days for the chemicals to be drawn down into the root of the plant.
Dish soap has the ability to lubricate and break down the bonds of fats and grease. When poured into the toilet, dish soap helps lubricate the waste causing the clog, while also breaking down its structure, allowing it to easily flow down the drain.
Highly fragrant bar soap, like Irish Spring, scattered around your yard and garden can repel many types of animals that have a delicate sense of smell. Gather old soap remnants and hang them from trees or around the perimeter of your garden to stop mice and deer.
