Answer:
- s + m + L = 78
- 0.45s +0.60m +0.75L = 46.95
- s - m + L = 4
Step-by-step explanation:
The problem statement asks for the number of each size cup sold. You are told there are three sizes, so it is convenient to use one variable to represent the number of cups of a given size that were sold—three variables total.The problem statements tell you the relationships between the numbers:
- the total number of cups sold
- the total value of cups sold
- the relationship between numbers of one size versus other sizes
It is appropriate to write an equation for each of these relationships, for a total of three equations. (Here, the last of these equations is put into standard form to make it easier to translate this to a matrix equation for solving by calculator.)
___
The solution is: 20 small, 37 medium, and 21 large.
Answer:

Step-by-step explanation:
Whatever number you multiply, it will still simplify to 7:4
Answer:
It cannot be answered if we don't figure out what x means. IF we knew what X is we can multiply 6 by x and then add 7.
an example would be if x was 3. we could figure out the answer by just doing (6*3)+7=25
