Sagot :
Answer:
Sus dimensiones son:
Cola: 18 cm
Parte media: 6 cm
Cabeza: 3 cm
Explanation:
Planteamiento:
c = 3m. Primer ecuación
z = m/2. Segunda ecuación
c + m + z = 27. Tercer ecuación
c = longitud de la cola
m = longitud de la parte media
z = longitud de la cabeza
Desarrollo:
Sustituyendo el valor de la primer y segunda ecuación en la tercer ecuación:
3m + m + m/2 = 27
6m/2 + 2m/2 + m/2 = 27
9m/2 = 27
m = 27*2/9
m = 6 cm
de la primer ecuación:
c = 3m
c = 3*6
c = 18 cm
de la segunda ecuación:
z = m/2
z = 6/2
z = 3 cm
Comprobación:
18 + 6 + 3 = 27
