Answer:
x = 4
Step-by-step explanation:
Make y the subject in both equations



For the second equation

The two equations are parallel because they have the same gradient or slope but different y intercepts.
This type of equations have no solution because they will never intersect.

The correct answer is C
The simplest interpretation would go a little something like this:
We know that we want the total donation amount to be more than $7,900, so we can set up this inequality to begin with

Where
D is the total donations raised (in dollars). How do we find D? Well, we just add up the total number of table reservations sold and the total number of single tickets sold. If we let
r stand for the number of reservation tickets and
s stand for the number of single tickets, then we have

So, the inequality representing this situation would be

And that would probably be fine for this problem.

</span>Of course, if this were a real-life scenario, we'd need to take some additional details into account: How many tables do we have? How many people can be seated at each table?
They are both the same. There are 60 seconds in one minute, so 60*3 is 180. Since 180=180, they are equal.

Answer:
Either :
1/2 10x+1/2 20y+1/2 10z
or
5x+10y+5z
Step-by-step explanation:
You're just multiplying everything by 1/2
