A is -12/15 (4/5)
B is 35/12
C is 56
D is 8/15
Sorry if any of these are wrong.
To check them, turn any mixed number into an improper fraction. Then, multiply by the reciprocal. Ex: 4/0 divided by 1/3
X reciprocal- 4/0 times 3/1
see so,1200 kg of coal=1kg of aluminum
if 1 soda can needs 15g of aliminium so
1200/15=80kg coal will be needed for 1 can of soda.

Answer:
<em>x = 1</em>
<em>y = 1</em>
Step-by-step explanation:
<u>System of Equations</u>
We are given the system of equations:
2x + y = 3
x = 2y - 1
Substituting x in the first equation:
2(2y - 1) + y = 3
Operating:
4y - 2 + y = 3
5y = 3 + 2
y = 5/5 = 1
y = 1
Since:
x = 2y - 1
Then:
x = 2(1) - 1
x = 1
Solution:
x = 1
y = 1
