Answer:

(13)

x= 8

y=11

(14)

x= 20

y=20.75

(15)

x=9

y=13

Step-by-step explanation:

(13) 8x-1 = 11x -25

24=3x

x= 8

8(8)-1 +15y-48= 180

15y=165

y=11

(14) 7x-44 + 4x + 4= 180

11x= 220

x= 20

4(20)+4+39= 8y-43

123=8y-43

166=8y

y=20.75

(15) 12x+1=15x-26

3x=27

x=9

28+15(9)-26+4y-9=180

4y=52

y=13

Si una persona de lunes a viernes entrena diariamente 1 hora ¿cuanto tiempo debe entrenar el sábado para que el promedio diario

mariarad [96]

Answer: 4 horas

Step-by-step explanation:

Una semana (de lunes a viernes) contiene 5 días

Si se entrena 1 hora por día:

1 x 5 = 5 horas (total de horas de entrenamiento de lunes a viernes)

Ese total más el número de horas que se entrena el sábado (x) dividido por 6 (numero de días en la semana incluyendo sábado) debe ser igual a el promedio de horas entrenadas en los 6 días (1.5)

(5+x) /6 =1.5

Despajando x:

5+x =1.5 x 6

5+x =9

x =9-5

x = 4 horas
