Answer:
Price in Japan= 17.81
Price in Switzerland = 13.58
Step-by-step explanation:
First set up system of equations
80.59 = 3j +2s
76.36 = 2j + 3s
Make it to where you can eliminate one variable
161.18 = 6j +4 s
-229.08 = -6j - 9s
Reset the problem
-67.9 = -5s
s=13.58
Re plug them in to the original equation to get j = 17.81
Answer:
The anwers Is C and E.
Step-by-step explanation:
A relationship between two quantities is proportional if the ratio between those quantities is always equivalent.
Hint #22 / 4
Let's look at the ratio between right- and left-handed students at East Middle School.

10.5 right-handed students for every left-handed student.
Hint #33 / 4
Now we can compare the other combinations of values for left-handed and right-handed students. Which ratios are equivalent to the ratio at East Middle School?
So the anwers is C AND E
Answer:
7x^-7, that is the answer
Answer:
b) no solution
Step-by-step explanation:
What you always want to do in this type of problem is to combine all of your "like terms," where like terms are the part of your equation that have the same variable (or no variable). In this equation, we see three terms that have the variable "z". We can add the 12z + 15z on the left side to get 27z, and then we subtract 27z on both sides to cancel both of the 27z terms out.
Now, we are left with -6 = -5 (because we got rid of all the terms with the variable z in them). We know that -6 does not equal -5, and therefore, there is no number that we can assign to variable z such that the left side of the equation will equal the right side of the equation.
Therefore, there is no solution (because a solution to the equation would be a value that we can plug into the variable z to make the equation true).
Answer:
$ 1850
Step-by-step explanation:
As it is simple interest, the interest will be same each year.
Interest = 2312.50 - 2081.25 = $ 231.25
The amount borrowed = 2081.25 - 231.25 = $ 1850
