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
Answer:
1) 5 ( 4h - 1 )
2) 5 ( 3r + 7 )
3) 2( -2p +5 )
Step-by-step explanation:
For no. 1 you have to find a <u>common factor (</u>a number that divides into both 20 and 5) which is 5 because 20 divided by 5 is 4 and 5 divided by 5 is 1. so you have to do 20h divided by 5 which is 4h (don't forget the h ! ) and you do -5 divided by 1 which is -1. Remember when you do any multiplying or dividing questions with negatives and positives :
minus + minus = minus (-5*-6 = -30)
positive + positive = positive (5*6 = 30) * equals multiplacation by the way
minus + positive = minus (-5*6 = -30)
positive + minus = minus (5*-6 = -30)
hope this helped xx
