Answer: Option 'd' is correct.
Step-by-step explanation:
Since we have given that
Volume of an excavation = 203 cubic feet
Weight of the material = 1200 pounds per cubic yard
So, the weight of the excavation would be
Volume of an excavation × Weight of the material

Hence, the weight of the excavation is 243,600 pounds.
Therefore, Option 'd' is correct.

Answer:
and 
Step-by-step explanation:
Given:
The rational equation to solve is given as:

We use the cross multiplication rule and multiply the numerators one side with the denominators of the other side. Therefore,

Now, for
, the rational equation is equal to 0. So,
is a solution.
Also,
is also a solution as the equation's denominator is defined at that point.
So, no extraneous solution.
