En 4 años, Jake será dos veces mayor que Jane. Actualmente, Él es tres veces mayor que Jane. ¿Cuántos años tendrá Jake en 5 años?

17 años

Step-by-step explanation:

Deje que la edad de Jane sea x

Deja la edad de Jake por y

y = 3x 1

y + 4 = 2 (x + 4)

y = 2x + 8 - 4

y = 2x + 4 2

x = y / 3 3

Sustituye 3 en 2

y = 2 (y / 3) + 4

Multiplicar por 3

3y = 2y + 12

3 años - 2 años = 12

y = 12

Pero y = 3x

Por eso;

x = 12/3

x = 4

Dentro de cinco años

Jake = 12 + 5 = 17años

for ex: the reciprocal of 3/4 is 4/3. it is the opposite.

reciprocal definition:

a mathematical expression or function so related to another that their product is one; the quantity obtained by dividing the number one by a given quantity.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
