(180 - 132)=48
I hope this help
Its simple
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:
81
Step-by-step explanation:
Using PEMDAS/BODMAS, we will have to do the exponent first, which is 
.
Substitute the variable z with 6, since z = 6.
.
Thus, we will get
Solve the multiplication next.
Finally, add/subtract the numbers:
Answer:
Step-by-step explanation:
I assume you mean simple linear equations, maybe not factoring. Anyhow Ill do a few examples:
1. 2x + 5 = 19
2. 14 - 3x = 23
3. 50x / 5 = 150
1. 2x + 5 = 19
Subtract 5
2x = 14
Divide by 2
x = 7
2. 14 - 3x = 23
Subtract 14 to the other side because we have to isolate the term with x in it
-3x = 9
Divide by -3
x = -3
3. 50x / 5 = 150
Multiply by 5 to isolate the value with x
50x = 750
Divide by 50
x = 15
I dont know if this is what you are looking for but this is general idea of how to solve these types of questions. If you need factoring or help with quadratics then let me know!
