Jane is 5 times as old as her sister. in 3 years jane will be twice as old as her sister. how old are they now?

jane is 5 and her sister is 1

Step-by-step explanation:

we don't know jane's sister age, so we will use x

she is 5 times as old as her, so jane is 5x

in 3 years, jane will be 2 times as old as her

so you add 3 to both their ages

then you set an equation. to make their ages equal, you multiple her sister's age by 2

you then get

5x+3=2(x+3)

5x+3=2x+6

x=1

Her sister is 1 and Jane is 5

the answer is:

mean: 6

mad: 2.14
