Answer:

The constant of proportionality is equal to 2.5.

Step-by-step explanation:

The given equation is .

Now, let's assume y is proportional to x.

Mathematically, it can be written as,

Now, to eliminate the sign of proportionality by equal to, it is required to introduce a constant term. It can be represented as,

Now, compare the given equation with the above equation,

The above comparison concludes that the constant of proportionality is equal to 2.5.

La Biblia dice que Matusalén vivió 979 años, mientras que Abraham vivió 175 años, escribe la fracción que indica la relación de
LenKa [72]

Answer:

A 175/979 = M

Step-by-step explanation:

Si Matusalén vivió 979 años y Abraham vivió 175 esto quiere decir que abraham vivio menos años que Matusalén.

Por lo que la fracción va a tener que ser menor que 1 ya que al multiplicarla por la edad de Matusalén nos tiene que dar la de Abraham.

Tenemos que encontrar una fraccion que multiplicada por 979 nos de 175.

979 * X = 175

Tenemos que despejar la x y encontraremos el valor de la fraccion.

979 * X = 175

X = 175/979

Nos fijamos si se puede simplificar, no se puede asique este es el resultado final.
