if you use the formula f=ma then the force of tension would equal the sum of the masses of the blocks multiplied by the acceleration of the system
now in number 10 it's asking for the tension in the cord. Since the system is moving to the right, then the blocks affecting the cord would be anything to the left of the cord.
So all you have to do is add up the mass of the blocks to the left of the cord, and multiply that number by the acceleration (you're answer to number 9). Number 11 is the same concept, but there's only one block this time.
