Solve this linear equation for p:<br> 2.6(5.5p – 12.4) = 127.92
Ymorist [56]
HI :)
First we must distribute the 2.6 to everything inside the () 

The new equation would then be
14.3p-32.24 = 127.92

Then you would add a -32.24 to each side of the equal sign, so that the 32.34 would become a zero pair on the right side of the equal sign and cancel. 

The new equation would then be
14.3p = 160.16

Then you divide each side of the = by 14.3, that way the p becomes isolated.
14.3p/14.3 = 160.16/14.3

Then you're left with 
p = 11.2

Hope this helped :)

La temperatura de un congelador bajó de 3 °C a −9 °C en 3 horas. Si la temperatura del congelador bajó en la misma cantidad de g
kolbaska11 [484]

Usando proporciones, se encuentra que al final de la primera hora, el congelador tenía una temperatura de -1ºC.

  • Este problema se resuelve por proporciones.
  • En 3 horas, la temperatura bajó 12ºC, puesto que 3 - (-9) = 12.

La temperatura del congelador bajó en la <u>misma cantidad de grados cada hora</u>, o sea, en la primera hora, la cantidad que bajo es:

\frac{12}{3} = 4

4ºC bajo a 3ºC es:

3 - 4 = -1

O sea, al final de la primera hora, el congelador tenía una temperatura de -1ºC.
