1. in 2 min you have 25 g
in 15 sec you loose 2.5 g
2. in 4 min you have 5 g
in 30 sec you loose 5 g
3. y=45x-10
y=80x-20
4. it takes 2 min and 15 sec to empty the first one and 3 min to empty the second one.
20(1-p)
20(1-0.25)
20(0.75)

Answer:
31 = x
Step-by-step explanation:
First multiply out
2x + 10 = 3x - 21
Now collect terms
10 + 21 = 3x - 2x
Simplify
31 = x
Hello,
The answer is x= y-13 / 2 ( everything after the x= is a fraction)
How to solve;
Start by subtracting 13 from both sides of y=2x+13, we do this to get the x on 1 side
So now we have y-13=2x
Next divide both sides by 2, we do this to get x by it self.
y-13/2=x
Now we flip the problem and there you have it!
Edit: The x does not have a Pos or neg value, The only way to know what x is, is to solve for x.
