Answer:
A, D, E (probably preferred)
B, C, F (also true)
Step-by-step explanation:
"This situation" problems are almost always ambiguous. The first problem is to figure out what it is about "this situation" that you want to model.
__
If we want to model concession stand revenue in a general way, then statements B, C, and F could represent "this situation." No specific values can be determined from this model.
__
More likely, we want to model the details of sales and revenue, so we want to know the exact numbers of water bottles and hamburgers that were sold. For "this situation," we can assign variables to the numbers of items of each type, and write equations for the total number of items and for the revenue their sales generates. Appropriate statements about this interpretation of the problem are those of A, D, and E:
A: x could represent bottles sold
D: y could represent hamburgers sold
E: The system of equations could be 2.50x +5.50y = 1325; x +y = 350.
_____
The solution to the last model is 200 bottles were sold for revenue of $500, and 150 hamburgers were sold for revenue of $825.
Answer:
7.5
Step-by-step explanation:
7.5 is greater than 7.05
The general form of the given equation is 3x-y=0.
The given equation is 
.
We need to write the given equation in a general form.
<h3>What is a general form of an equation?</h3>
The general form of any equation contains the degree of variables in decreasing order. The general form of a linear equation is ax + b = 0.
That is, 
.
Hence, the general form of the given equation is 3x-y=0.
