If you would like to solve the system of equations x + y = 3 and 2x - y = 6, you can do this using the following steps:
<span>x + y = 3 ... y = 3 - x
2x - y = 6
</span>_________
<span>2x - y = 6
</span>2x - (3 - x) = 6
2x - 3 + x = 6
3x = 6 + 3
3x = 9 /3
x = 9/3
x = 3
<span>y = 3 - x = 3 - 3 = 0
</span>
The correct result would be x = 3.
Answer:
28.26ft^2
Step-by-step explanation:
The formula for area of circle is:
A=3,14*r^2, where r =3 and 3,14 is pie number, so we have

Answer:
Total money get from soda cans = $259.2
Step-by-step explanation:
Given:
Number of soda cases = 18
Number of soda can in each case = 24
Price of each soda can = $0.60
Find:
Total money get from soda cans
Computation:
Total money get from soda cans = Number of soda cases x Number of soda can in each case x Price of each soda can
Total money get from soda cans = 18 x 24 x 0.60
Total money get from soda cans = $259.2
