Cynthia is 6 times as old as Rebecca. In 6 years, Cynthia will be only 3 times as old as Rebecca. How old is Rebecca now?

16 y.o

Step-by-step explanation:

say rebecca = x

therefore, cynthia = 6x

when rebecca ages 6 years (x+6), cynthia will be 3(x+6) years old

since cynthia's original age + 6 will be equal to the new expression of her age after 6 years

3x + 18 = 6x + 6

18 = 3x + 6

3x = 12

x = 4

as cynthia = x + 6 (NOTE: AT THE BEGINNING) her original age was 10.

however after 6 years she's 16

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

b and c
