B and c I believe ..........
Hello from MrBillDoesMath!
Answer:
Choice A, 18x - 6y = 20
Discussion:
Given line
-9x + 3y = 12 (M)
Choice A:
18x - 6y = 20 => divide both sides by -2
-9x + 3y = -10 (N)
The left hand sides of (M) and (N) are equal implying that right hand sides are equal which further implies 12 = -10. Contradiction! so the system M and N has no solution.
Thank you,
MrB
Answer: 15
Step-by-step explanation: Perimeter is adding the width and the length together. For a rectangle, it has four sides, so it has two lengths and two widths. The width is 10, so you add 10 + 10 which is 20. The length of the rectangle would be 15 since 15 + 15 is 30, and then 30 + 20 = 50, the perimeter.

Answer: 324 grams</h3>
Work Shown:
(540 grams sugar)/(5 liter soda) = (x grams sugar)/(3 liter soda)
540/5 = x/3
540*3 = 5*x
1620 = 5x
5x = 1620
x = 1620/5
x = 324
3 liters of soda has 324 grams of sugar
