Answer:
x = $3.50; y = $2.25
Step-by-step explanation:
First, come up with your two equations where x= price of walnuts and y= price of chocolate chips: 8x + 4y = 37 and 3x + 2y = 15. Solve the first equation.
3x + 2y = 15
3x = 15 - 2y
x = (15 - 2y)/3
Plug in the answer to your second equation.
8(15 - 2y)/3 + 4y = 37
(120 - 16y)/3 + 4y = 37
120 - 16y + 12y = 111
120 - 4y = 111
-4y = -9
y = 2.25
Plug in your answer to find <em>x.</em>
3x + 2(2.25) = 15
3x + 4.5 = 15
3x = 10.5
x = 3.5
Check your equation.
1) 3(3.5) + 2(2.25) = 15
10.5 + 4.5 = 15
15 = 15
2) 8(3.5) + 4(2.25) = 37
28 + 9 = 37
37 = 37
Answer:
The Number is -8.
Step-by-step explanation:
Let the number be x.
Now given:
A number decreased by twelve;
It means 12 is subtracted from the number.
Hence the equation can be framed as;
Also given;
twice the opposite of ten
Opposite of 10 = -10
Twice the opposite of 10 means 2 is multiplied with opposite of 10.
Hence twice the opposite of ten =
Now A number decreased by twelve is twice the opposite of ten
framing it in equation form we get;
Solving the above equation we get;
Hence the Number is -8.
