Justin is 2 years older than one third Marcella’s age. Aimee is four years younger than 2times Justin’s age. Define a variable a

spin [16.1K]

Let's assume

Marcella’s age is x

now, we are given

Justin is 2 years older than one third Marcella’s age

so, Justin's age will be

$=2+\frac{1}{3} x$

Let's assume Justin's age is J

so, we get

$J=2+\frac{1}{3} x$

Aimee is four years younger than 2times Justin’s age

so,

Aimee's age will be

$=2J-4$

now, we can plug J

$A=2*(2+\frac{1}{3} x)-4$

now, we are given

Marcella is 63 years old

so, x=63

we can plug x=63 and find A

$A=2*(2+\frac{1}{3} *63)-4$

$A=42$

so,

Aimee's age is 42 years

$J=2+\frac{1}{3} x$

now, we can plug x=63

$J=2+\frac{1}{3} *63$

$J=23$

so, Justin's age is 23 years

Which ratio forms a proportion with 25/35 . A. 3/5 B. 15/21 C.24/34 D. 5/11

iogann1982 [59]

In order to find this out, we just needed to find out which one has the same smallest fraction

25 / 35. Divided this by 5 and we will get 5/7 >>> smallest fraction

15/21 . Divided this by 3 and we also will get 5/7 >> smallest fraction

So the answer would be : B. 15/21

hope this helps
