FernandongBuenas tardes Cristina,
Te pongo mis respuestas:
1) x4
3)
a) x/2-10x/2 +5
c) x(x+1)<8
d) 2(x+3)+2x<50
Nerea1) x4
3) Traduce:
a) x/2 – 10 x/2 +5
c) x*(x+1) < 8
d) 2(x+x+3) < 50 = 4x + 6 < 50
x =11
SRTEn la 1 se me pasó cambiar de signo me daría x44; x>4
beatriz.cuadradoLa respuesta 6 esta mal, no es el área lo que pide , es el perímetro. 2(a+3) x 2a > 50 siendo a la altura y (a+3) base
beatriz.cuadrado2(a+3) x 2a<50 así esta bien. Que había cambiado el signo.
Tutora Cristina AlbalaBuenas tardes, ¡futur@s funcionari@s!
¡Cómo suena eso eh, se me pone el vello de punta solo al escribirlo! Pasos firmes y lo conseguiremos.
Quiero daros las gracias a tod@s por vuestra participación en el foro, en estas actividades, os dejo las soluciones a los ejercicios planteados de inecuaciones, al igual que os voy a subir un vídeo con una explicación sobre ellos a la UT11:
[b]1. x 4[/b]
[attachment=798]Lenguaje algebraico.png[/attachment]
En el [b]apartado 3.d)[/b] [u]también es admisible la expresión 2x + 2(x+3) < 50 atendiendo a la literalidad del enunciado[/u], pero si quiero que tengamos en cuenta que, ante la resolución de un problema de [color=orange]PERÍMETROS[/color] o [color=blue]ÁREAS[/color] cuidaremos MUCHO las UNIDADES.
Un saludo, gracias.
