The ratio of the ages of two sisters are 4:3. The older sister is three years older than the younger sister. How old is the younger sister?​

The Younger sister is 9

Step-by-step explanation:

x = age of older sister

x - 3 = age of younger sister

4/3 = x/(x - 3)

Solve for x.

4(x - 3) = 3x

4x - 12 = 3x

x = 12

The older is 12, the younger is 12 - 3 = 9

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
