Let’s denote the number as x, then
x/12 <= 6
x <= 6 times 12
x <= 72
We are required to tally the number of games scoring 15, 16, 17, and 18. There are 3 games with a score of 15, 2 games scoring 16, 5 games with a score of 17, and 3 games scoring 18. The total comes to 13 games.
Finding a solution to an equation entails determining the value of x that renders the equation valid.
We must reverse the operations applied to x to isolate it.

Final Note:
The resulting equation is false, indicating that there is NO solution. Graphically, both equations will be represented as parallel lines that do not intersect.
With a height exceeding 550 meters, the CN Tower held the title for the tallest free-standing structure globally until the Burj Khalifa was completed in 2010, reaching 828 meters, making it the largest man-made structure ever.
The measurement of arc DB equals 74.57°. Step-by-step explanation: To clarify the resolution method: A secant intersects a circle in precisely two points, while a tangent intersects at just one point. When a tangent and a secant intersect outside of a circle, the formed angle's measurement is precisely half of the positive difference between the measures of the intercepted arcs. Now, applying this to the issue where secant CE intersects circle A at points D and E, while tangent CB touches circle A at B, forming angle ECB. As such, m∠ECB = 1/2 (m arc EB - m arc DB). Given m arc EB as 96° and m arc DB given as 25x + 21, along with m∠ECB as 5x, we establish the equation 5x = 1/2[96 - (25x + 21)]. After rearranging and solving, we find x = 75/35, simplifying to 15/7. Next, substituting x back into the arc DB formula gives m arc DB = 25(15/7) + 21 = 522/7 yields approximately 74.57°.
