We are given
Mala is y years old
So, Mala =y
her sister is 4 years older than Mala
So, Sister =y+4
now, we can find sum
Sum = Mala +Sister
Sum = y +y+4
Sum = 2y+4...............Answer
Since y varies inversely as x , the equation is y=k/x....... Then you plug in 2 for y and 25 for x to find K....... After that you get K= 50...... Then plug in 50 for K and 40 for y then solve for x....... After that you get X= 1.25
The simplified expression would be:
10-2t
If the ratio is 7:4
Then you could cross multiply and get 56:32
