Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form 
The ratio between the two variables is a constant called constant of proportionality k

<u><em>Verify each case</em></u>
A) Julie sold 4 necklaces for $12 and 9 necklaces for $25.

Multiply in cross
Is not true
therefore
The situation not represent a proportional relationship

Answer:
NQ = 13.5
Step-by-step explanation:
The diagonals of a parallelogram bisect each other. NQ is half of NP, so is ...
NQ = PN/2 = 27/2
NQ = 13.5
1. The information given in this problem, is:
- <span>Wayne went on a 4 km hike.
- </span>Wayne took a break at 4/3 km.
- Wayne took a drink of water at 10/3.
2. Then, when you convert the values from fractions to decimals, you have:
4/3 km=1.33 km
10/3 km=3.33 km
3. With this values, you can make the number line and show <span>his starting and finishing place, and the 2 points where he stopped. This is shown in the figure attached.</span>
