How many rivers from Texas empty directly into the Mississippi River?
Yes. The Red forms the northern border of Texas, goes through Louisiana and dumps into the Mississippi. The next two rivers south dump into the Red just into Louisiana The Sabine the next river down forms much of the eastern border of Texas, and dumps into the Gulf of Mexico, thus blocking any other rivers from getting to the Mississippi. If you want to get really picky, the Canadian River, which flows through the panhandle, goes into Oklahoma and joins the Arkansas which flows into the Mississippi, but that doesn’t make the Canadian a tributary of the Miss.
