Answer: he bought 12 books.
Step-by-step explanation:
Let x represent the number of books that Greg bought.
Greg ordered some books online for $6 each. This means that x books would cost $6x
He paid a total of $3 for shipping. The total cost of the purchase was $75.00. This means that
6x + 3 = 75
Subtracting 3 from the left hand side and the right hand side of the equation, it becomes
6x + 3 - 3 = 75 - 3
6x = 72
Dividing the left hand side and the right hand side of the equation by 6, it becomes
6x/6 = 72/6
x = 12

Usando la relación:
Altura de la persona / sombra de la persona = altura del poste / sombra del poste
1,75 / 1,35 = x / 21
Cruz multiplicar
1,35 * x = 1,75 * 21
x = (1,75 * 21) / 1,35
x = 27,22
