Knowing that x varies directly with y, we know the basic skeleton of the equation is y = mx.
To find m, plug in the known coordinate (8,10), where the x-coordinate is 8 and the y-coordinate is 10.
Then, plug in m to the equation to get y = (5/4)x.
Finally, plug in the y-coordinate 18 to the equation and solve for x!
Your exact answer is x = 72/5. However, if your teacher prefers decimals, then x = 14.4
Hope this helps!

Step-by-step explanation:
we know that
<u><em>Combinations</em></u> are a way to calculate the total outcomes of an event where order of the outcomes does not matter.
To calculate combinations, we will use the formula
where
n represents the total number of items
r represents the number of items being chosen at a time.
In this problem
substitute
