Gio's father is 5 times as old as him. And his sister Mary is half as old as him. In two years, the sum of all their ages will be 58. How old is go now? ​

Sagot :

F = 5J

J = 2M

(F+2)+(J+2)+(M+2)= 58

F + J + m = 52

5J + J + 0.5J = 52

13/2 J = 52

J = 52 * 2/13 = 8 years, John’s age now.

I hope this helps :D

Answer:

8 yrs. old

Step-by-step explanation:

let x be Gio's age now , then

Gio's father is 5x yrs. old and his sister is [tex]\frac{x}{2}[/tex] yrs. old, in two years, which means all their ages increased by two, the sum of their ages is 58 so,

Gio's age is x+2

His Father is 5x+2

and mary's is [tex]\frac{x}{2} + 2[/tex]

adding them should yield 58

[tex]x+2+5x+2+\frac{x}{2}+2=58\\ \frac{13x}{2} + 6 = 58\\\frac{13x}{2} = 52\\13x = 104\\x = 8[/tex]
