Answer:
Step-by-step explanation:
The system of equations is expressed as
-x -3y =18 - - - - - - - - - - - - - -1
x + 2y = -14 - - - - - - - - - - - - - -2
We would eliminate x by adding equation 1 to equation 2. It becomes
- y = 4
Dividing the left hand side of the equation and the right hand side of the equation by - 1, it becomes
- y/ - 1 = 4/ - 1
y = - 4
Substituting y = - 4 into equation 1, it becomes
-x -3 × - 4 =18
- x + 12 = 18
Subtracting 12 from the left hand side of the equation and the right hand side of the equation, it becomes
- x + 12 - 12 = 18 - 12
- x = 6
x = - 6
Answer: 30.5
Step-by-step explanation:
Given :
Coffee cost in a paper cup , $1.50 .
Coffee cost in a cremic mug , $6 .
Refills of the ceramic mug are $1 .
To Find :
How many refills do you need to buy to make buying the mug a better value
then buying individual paper cups of coffee.
Solution :
Let , number of fills to make mug better option is x .
So , money spend in mug in greater than paper cup .
Therefore , after 12 cups of coffee, ceramic mug will have better value than paper cups .
Hence , this is the required solution .
