The answer to your question is 25 minutes.
An hour is 60 min so 1/3 of that would be 20 min. which is how long Jenny spent texting her friend. 1/4 would be 15 min in which she spent brushing & putting on pajama's. If she spent the rest of her hour reading that means she must of read for 25 min, which you could find out by adding the 20 and 15 min she's already spent and then subtracting it from the total time 60 min
1/3 of an hour=20 min
1/4 of an hour=15 min
20 min+15 min= 35 min
60 min-36 min= 25 min
Hope this helps! :)
/Answer:
the verry last one
Step-by-step explanation:
Respuesta:
2x - 0.5x = 30
x = 20
Explicación paso a paso:
Llamemos "x" a la incógnita, el número desconocido.
Cuando nos referimos al doble de un número, es lo mismo que 2x.
Cuando nos referimos a la mitad de un número, es lo mismo que 0.5 x.
Consideremos que al doble de un número (2x) se le resta su mitad 0.5x) y se obtiene 30. La ecuación resultante es:
2x - 0.5x = 30
1.5x = 30
x = 30/1.5 = 20
Answer:
x > -3
Step-by-step explanation:
5x+ 7 > 2(x-1)
Distribute the 2 on each side
5x+7 > 2x -2*1
5x+7 > 2x-2
Subtract 2x from each side
5x-2x +7 > 2x-2x-2
3x + 7>-2
Subtract 7 from each side
3x+7-7>-2-7
3x>-9
Divide by 3 on each side
3x/3 >-9/3
x > -3
Answer:
y = 1 x = 3
the +1 at the end of the equation is the y intercept while the number with the x is the slope, since the slope is -1/3 take it as if it was rise/run. In other words since the rise is -1 you are going down 1 unit and the run is 3 you are going 3 units to the right & that's the path its going to be taking. So that makes the line cross the x axis at (0,3)
