An octagon would have 8 vertices.
Solve: 12 - 2x = -2(y - x)
Steps:
1. Expand -2(y - x): -2y + 2x
12 - 2x = -2y + 2x
2. Then subtract 12 from both sides
12 - 12 - 2x = -2y + 2x - 12
3. Simplify,
-2x = -2y + 2x - 12
4. Then, subtract 2x from both sides
-2x - 2x = -2y + 2x - 2x - 12
5. Simplify,
-4x = -2y - 12
6. Then, divide both sides by -4
-4x/-4 = -2y/-4 - 12/-4
7. Simplify,
x = 1/2y + 3 <======= <em>Answer</em>

Answer:
1000 : 269 : 47
Step-by-step explanation:
A ratio is a way of comparing the value or amount of one quantity to another.
We are to find the ration of water to sucrose to saline solution, hence, it must remain in that order.
Water : Sucrose : Saline solution
The amount of water is 1 litre (1 * 1000 ml = 1000 ml)
The amount of sucrose is 269 ml
The amount of saline solution is 47 ml
Therefore, the ratio of water to sucrose to saline solution is:
W : S : SS = 1000 : 269 : 47
Since 1000, 269 and 47 have no common factors, that is the simplest form of the ratio.
