Use the following values for the arrows in the drawing: a = 185 J of heat; b = 45 J of heat; c = 115 J of work; d = 40 J of work; e = 65 J of work; and f = 190 J of heat. Find the change in the internal energy of object A only.
Use the First Law of Thermodynamics Be careful with sign conventions.

I have no idea what this looks like.
Use dE = q + w
q will be joules of heat. If the arrow goes INTO the object it is +, if OUT OF the object it is -.
Same sign convention for work. If the arrow goes INTO the object it is +w; if out of the object it is -w.
