Answer:
1000 : 199 : 271
Step-by-step explanation:
A rations a form of comparison between different variables or quantities.
We want to compare how much water, sucrose and saline solution are used to make the medicine.
The amount of water used is 1 L = 1000 mL
The amount of sucrose used is 199 mL
The amount of saline solution used is 271 mL
Therefore, the ratio of water to sucrose to saline solution is:
1000 : 199 : 271
This is the simplest form because 1000, 199 and 271 do not have any common factors.
First you must add the same numbers together, for instance, you wouldn't add 4y with 4 you have to add it with another number that is just like it, for instance 4y and 9y they are the same, so you can add them. So let's get to the problem now:
5y(2y-3)=(2y-3)
5y*2y=10y
(10y-3)=(2y-3)
You can do nothing to the other side because there are no numbers, that are the same.
Let's check
3m - 9 = 9+3m
collect like terms
3m -3m = 9 + 9
0m = 18
which is not possible, so it will not have any solutions
So we have:
xk = v + w solve for x
divide both sides by k to isolate the variable x:
x = (v+w)/k
^^This is your answer!
