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

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
