Answer:
Using the table
Maria does 1/4 of the job in 1 hour since it takes her 4 hours to complete the job , she works x hours and completes x/4 of the task
Josie does 1/2 of the job in 1 hour since it takes her 2 hours to complete the job , she works x hours and completes x/2
x/4 + x/2 = 1 completed task
Multiply by 4
x/4 *4 + x/2*4 = 1*4
x+2x =4
3x=4
x = 4/3
x = 1 1/3 hours

Answer: 
Step-by-step explanation:
1. To find the equation asked, you must add the times:

Where
is the time takes Lilly in her path to work and
is the time takes Lilly in her path to home.
2. You must use the following formula of speed and solve for the time

Where n is the distance, V is the speed and t is the time.
3. You know that Lilly takes a train each day to work that averages 35 miles per hour, then, you can write the following expression:

4. And her train ride follows the same path at 45 miles per hour:

5. Then, you obtain the following equation:

Answer:
-2
Step-by-step explanation:
Hello,
First of all, let's check the denominator.

Now, let's see the numerator.

So we cannot factorise the numerator with (x+2) or (x-3)
Then, -2 and 3 are the the discontinuities of the expression.
There is only -2 in the list, this is the correct answer.
Hope this helps.
Do not hesitate if you need further explanation.
