1 answer:

4 0

This is how I would do it! You can use any coordinates to find the gradient, and you can sub any in for the equation of a line. Try practicing q. 6 by yourself so you can get the hang of it! Let me know if you don’t understand any of the steps :)

the ratio of sadia's age to her father's age is 3:6. The sum of their age is 96 .What is sadia's age

max2010maxim [7]

We have,

$a:b=3:6,a+b=96$

Introduce variable $x$ such that $a=3x,b=6x$

The sum $a+b=96$ is therefore $9x=96\implies x=10.\overline{6}$

So,

$a=3\cdot10.\overline{6}=\boxed{32}$ (sadia's age)

$b=6\cdot10.\overline{6}=\boxed{64}$ (father's age)

Hope this helps :)
