Calculate the number of vans needed by dividing the number of people that need transported by the capacity of one van:

vans = \( \frac{54}{12} \) = 4\(\frac{1}{2}\)

So, it will take 4 full vans and one partially full van to transport the entire team making a total of 5 vans.

A ratio of 5:1 means that there are 5 home fans for every one visiting fan. So, of every 6 fans, 5 are home fans and \( \frac{5}{6} \) of every fan in the stadium is a home fan:

43,000 fans x \( \frac{5}{6} \) = \( \frac{215000}{6} \) = 35,833 fans.

If 73% of the town's 43,000 voters cast ballots the number of votes cast is:

(\( \frac{73}{100} \)) x 43,000 = \( \frac{3,139,000}{100} \) = 31,390

The mayor got 53% of the votes cast which is:

(\( \frac{53}{100} \)) x 31,390 = \( \frac{1,663,670}{100} \) = 16,637 votes.

Use PEMDAS (Parentheses, Exponents, Multipy/Divide, Add/Subtract):

2 + (3 + 4) ÷ 5 x 2 - 4²
P: 2 + (7) ÷ 5 x 2 - 4²
E: 2 + 7 ÷ 5 x 2 - 16
MD: 2 + \( \frac{7}{5} \) x 2 - 16
MD: 2 + \( \frac{14}{5} \) - 16
AS: \( \frac{10}{5} \) + \( \frac{14}{5} \) - 16
AS: \( \frac{24}{5} \) - 16
AS: \( \frac{24 - 80}{5} \)
\( \frac{-56}{5} \)
-11\(\frac{1}{5}\)

A prime number is an integer greater than 1 that has no factors other than 1 and itself. Examples of prime numbers include 2, 3, 5, 7, and 11.
