Question

Today, Isaac needs to walk his dog, water the garden, and feed his fish. D is the number of minutes it takes

to walk his dog, G is the number of minutes it takes to water the garden, and F is the number of minutes it


takes to feed his fish.


The expression G + D + F describes the total number of minutes it takes Isaac to do all three tasks.


We can also use the expression (G+D) + F to represent the same quantity.

Answer 1

The total minutes of the inside tasks: F

The total minutes of the outside tasks: G + D

The total minutes of the tasks involving animals: D + F

The total minutes of the tasks not involving animals: G

Explanation:

For reference:

1. D is the number of minutes it takes to walk his dog
2. G is the number of minutes it takes to water the garden
3. F is the number of minutes it takes to feed his fish.

Inside task(s): feeing fish

Outside task(s): Watering garden and walking dog

Task(s) involving animals: Walking dog and feeding fish

Task(s) not involving animals: Watering garden

The above is basically our answer. We now need to put it in terms of F, G, and D (This will be in the same order as the above):

1. F
2. G and D
3. D and F
4. G

Now, if you look at the very top with answer, you will see it's the same letters as what we just did. I hope this helps!
