2/3 = x/(3x + y)

Cross multiply:

3x = 2(3x + y)

Distribute 2:

3x = 6x + 2y

Subtract 6x to both sides:

-3x = 2y

Divide 'y' to both sides:

-3x/y = 2

Divide -3 to both sides:

x/y = -2/3

2/3 = x/3x + y
2(3x + y) = 3x
2(3x) + 2(y) = 3x
 6x + 2y = 3x
 - 6x - 6x
 2y = -3x
 2 2
 y = -1.5x

There are $\frac{1}{3}$ gallons of lemonade.

Two friends share the lemonade.

To solve you do kcf or keep change flip.

You keep $\frac{1}{3}$ and change division to multiplication.

Then $\frac{2}{1}$ is changed to $\frac{1}{2}$

The answer would be $\frac{1}{6}$

Answer:

The relationship is positive.

The model predicts a score of 60.

Not sure what part b is.

Step-by-step explanation:

Since while the money spent on advertising increases while the items sold increases, we have a positive relation between both variables.

By looking at where 30 is on the graph, we can see it lines up with 60,the middle between $40 and $80 on the y axis and so we know this is the cost associated with this value.
