PLEASE HELP QUICK I WILL MARK BRAINLIEST!

The answer to your question is the last option because the total of the whole table is 1.0. And, mathematically speaking, y cannot possibly be 1.0 if the tables values all add up to 1.0

La suma de las edades de tres personas es 127años. La mayor tiene 30 años mas que la menor y la del intermedio 26 menos que la m
Over [174]

Answer:

La mayor tiene 61 años.

Step-by-step explanation:

Sea x,y,z la edad de la mayor, intermedio y la menor respectivamente.

Tenemos las siguientes ecuaciones:

x+y+z=127 (la suma de las edades es 127)

x = z+30 (la mayor tiene 30 años más que la menor)

La frase "y la del intermedio 26 menos que la menor" no tiene sentido, puesto que esto implicaría que la del intermedio es menor que la menor. Luego se asume que la frase ha de ser "y la del intermedio 26 menos que la mayor"

x-26 = y (la del intermedio tiene 26 menos que la mayor).

La segunda ecuación se traduce a x-30 =z. Si reemplazamos todo en la primera ecuación obtenemos

x+(x-26)+(x-30) = 127

Obtenemos la ecuación

3x-56 = 127

Sumando 56 a ambos lados y dividiendo por 3, obtenemos

x = \frac{127+56}{3} = 61

Es decir la mayor tiene 61 años.
