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:
132
Step-by-step explanation:
11 / 5 = 2.2
2.2 x 60 = 132
Answer:
237?
Step-by-step explanation:
Well you have cut it into smaller pieces so it would be I guess 4 grams now because 20 divided by 5 is 4.
1] y - 3x = -8
[2] y + 9x = 4
-3x + y = -8 9x + y = 4
Solve equation [2] for the variable y
[2] y = -9x + 4
// Plug this in for variable y in equation [1]
[1] (-9x+4) - 3x = -8
[1] - 12x = -12
// Solve equation [1] for the variable x
[1] 12x = 12
[1] x = 1
// By now we know this much :
y = -9x+4
x = 1
// Use the x value to solve for y
y = -9(1)+4 = -5
{y,x} = {-5,1}
