Explicación paso a paso:
Datos:
[tex]media = 3.5 \\ nota1 = 4.4 \\ nota2 = 2.4 \\ nota3= 3.5 \\ nota4 = x[/tex]
[tex]media = \frac{nota1 + nota2 + nota3 + nota4}{4} [/tex]
Remplazando:
[tex]3.5 = \frac{ 4.4 + 2.4 + 3.5 + x}{4} [/tex]
[tex]x = 3.5 \times (4) - 4.4 - 2.4 - 3.5[/tex]
[tex]x = 3.7[/tex]
Respuesta:
43+24+35 ÷3 = 3.5
35×4 - 24-44-35
= 3.7
