46.19 should be the answer
Answer:
Por ejemplo, podrías utilizar la división para determinar cómo repartir 40 ... 15 ÷ 5 = 3. Podrías también usar la recta numérica para modelar ésta división. ... ¿Cuáles de las siguientes expresiones representan dividir $56 en partes iguales entre 7 ... “5, 10, 15, 20, 25, 30. Debo saltar 6 veces para llegar a 30.” 30 ÷ 5 = 6.

Step-by-step explanation:
Your question isn't complete but I believe that you want to know the number of rides that Katie can take.
Based on the information in the question, we can form an equation. Let the number of rides that Katie can take be represented by x. Therefore,
12 + (1.25 × x) = 50
12 + 1.25x = 50
1.25x = 50 - 12
1.25x = 38
x = 38/1.25
x = 30.4
Therefore, Katie can take at most 30 rides.
M + f + a = 82
m = 7a + 1
f = 1/2m.....f = 1/2(7a + 1).....f = 3.5a + 0.5
7a + 1 + 3.5a + 0.5 + a = 82
11.5a + 1.5 = 82
11.5a = 82 - 1.5
11.5a = 80.5
a = 80.5 / 11.5
a = 7......7 adults
m = 7a + 1
m = 7(7) + 1
m = 49 + 1
m = 50 <=== 50 male students
f = 1/2m
f = 1/2(50)
f = 25 <=== 25 female students
