Answer: OPTION C.
Step-by-step explanation:
Given a System of equations, you can use the Elimination Method to solve it by transforming the system in order to cancel out one of the variables. But first, the terms of both equations must be written in the same order.
To cancel out one of the variables, the coefficients must be opposites, which means that one must be positive and the other one must be negative.
Given the following System of equations:
You can notice that the order of the terms is not the same, so, if you want to use the Elimination Method to solve the system of equations, the first step you must apply is to rewrite the equations so like variable terms are in the same order.
Then:
Answer:
of the distance
Step-by-step explanation:
We know that a ferry traveled of the distance between two ports in
hours.
In order to calculate what fraction of the distance between the two ports can the ferry travel in one hour we can do the following reasoning :
The rate of the ferry is the same at any time.
The ferry will travel of the distance in
hours.
If we divide each fraction by 3 ⇒
and
We do this to obtain a ''1'' in the numerator of the second fraction (the hours fraction). Now, we can say that :
The ferry will travel of the distance in
hours.
Finally, we multiply each fraction by 7 (in order to obtain the distance for 1 hour) ⇒
and
We found out that the ferry will travel of the distance in 1 hour.
