Choice A) 2/3 of a pound

===========================================

Here's one way to think of it

Imagine you had a cake that is cut into thirds (see figure 1 below). One full cake has 3 pieces. So three full cakes have 3*3 = 9 slices all together.

This means 3 = 9/3

Add on an extra slice (an extra one-third) and we get 9/3+1/3 = 10/3

So the mixed number 3 & 1/3 is the same as the improper fraction 10/3

---------------

Now refer to figure 2. This is where we group up the ten slices into five groups. So there are 10/5 = 2 slices per container. Each slice is a third, so each container gets 2/3 a pound.

.

step-by-step explanation:

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
