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.

80% of x is equal to 100. Write an equation that shows the relationship of 80%, x, and 100
wariber [46]

Answer:

<u>The number is 125 and the equation is 0.8x = 100</u>

Step-by-step explanation:

80% of x is equal to 100.

Write an equation that shows the relationship of 80%, x, and 100

80% = 0.8

0.8x = 100

x = 100/0.8

x = 125

<u>The number is 125 and the equation is 0.8x = 100</u>
