When a skateboarder starts from rest and moves down a hill with constant acceleration in a straight line for 6 seconds in a second trial he starts from rest and moves along the same straight line with the same acceleration for only 2 seconds. His displacement from his starting point compared with the first trial is one-ninth as large. This will make the answer choice C.

Answer:
[3x + (y/2)]
Step-by-step explanation:
English Translation
Suppose we have x confirmed cases of coronavirus and y suspected cases. A - If the confirmed cases triple and half of the suspects fall, we will have the following expression to represent the total number of cases:
Solution
Number of confirmed cases = x
Number of suspected cases = y
Number of confirmed cases triples and becomes 3x
Half of the suspected cases fall and becomes (y/2)
Total number of cases then becomes
[3x + (y/2)]
In Portugese/Em português
Número de casos confirmados = x
Número de casos suspeitos = y
O número de casos confirmados triplica e se torna 3x
Metade dos casos suspeitos cai e se torna (y / 2)
O número total de casos passa a ser
[3x + (y / 2)]
