The answers to these questions can seem pretty confusing until you remember one simple rule. The tropical revolving storm itself is a low pressure, and so rotates according to the hemisphere it is in. However, in terms of which way it moves, it follows the isobars around the high pressure that it is adjacent to. So, for hurricanes affecting the east coast of America, this will be the Azores high, in the centre of the Atlantic. Winds flow clockwise around a high in the northern hemisphere. This is why hurricanes run (initially) east to west across the Atlantic, then generally north/north west towards America, then north east across the Atlantic. This is also why the tail end of hurricanes sometimes affect the UK, such as Lorenzo in 2019.
