The Mayan and other Mesoamerican cultures used a vigesimal number system based on base 20 (and, to some extent, base 5), probably originally developed from counting on fingers and toes. The numerals consisted of only three symbols: zero, represented as a shell shape; one, a dot; and five, a bar.

Las plantas y animales terrestre tienen estructuras de sostén mas rígidas que los acuáticos, porque pasa esto?
Aliun [14]

Answer:

La presión del agua es una de las razones.

Explanation:

Una gran razón de esto es la presión presente en el agua. El agua es más pesada que el aire, por lo que a presiones más profundas se vuelve más difícil para ciertos animales funcionar. Para dar cuenta de esto, muchos organismos y plantas dentro del agua se desarrollan para no tener esqueletos, ciertos órganos y otras partes del cuerpo que limitan su existencia en el agua. Las medusas son un buen ejemplo de esto.

U_____________W________________V
UV=13
UW=2y-9
WV=y-5

UV=UW+WV
UV=(2y-9)+(y-5)=2y-9+y-5=3y-14

13=3y-14
27=3y
y=27/3=9

Solution is A, y=9
