C. 9
If 9 friends come then they all get 4 water balloons and 9 beads (36/9=4, 81/9=9)
The answer can't be D. 10 as 36/10 and 81/10 do not equal whole numbers and her friends can't have a fractional number of water balloons or beads
Correct answer is D.
Graph passes through the point (-1, 0).
Therefore, x = -1 and y = 0.

This is the only equation which is true for x = -1 and y = 0.
Therefore, the solution is
<span>120 - 36 is 84 just as 12(10 - 3) = 12 x 7 = 84.</span>
The graph that shows a unit rate of 3/4, which is the time Cindy reads while riding in the car is the graph attached below.
<h3>What is Unit Rate?</h3>
Unit rate can be described as a constant or exactly how much of one quantity is per 1 unit of another quantity.
Unite rate (k) = x/y.
In the graph attached below, when x (hours driving) = 3, y (hours reading) = 4.
Therefore, unit rate = 3/4. We can then conclude that the graph that shows that Cindy reads 3/4 of the time she rides in a car is the graph attached below.
