Bogdan [553]

Answer:

$x = \dfrac{5}{2} \pm {\dfrac{\sqrt{57}}{2}$

Step-by-step explanation:

$x^2 - 5x = 8$

$x^2 - 5x + \dfrac{25}{4} = 8 + \dfrac{25}{4}$

$(x - \dfrac{5}{2})^2 = \dfrac{57}{4}$

$x - \dfrac{5}{2} = \pm \sqrt{\frac{57}{4}}$

$x = \dfrac{5}{2} \pm {\dfrac{\sqrt{57}}{2}$

Three years ago , Ahmed was one third of his sister's age. In a years time ,Ahmed's age doubled will match his sisters age. How

Black_prince [1.1K]

Let the age of ahmed three years ago be x years old. since 3 years ago ahmed as one third of his sister's age, his sister would be 3x years old 3 years ago.

in a year's time, ahmed would be x+4 years old and his sister would be 3x+4. we also know that in a year's time ahmed's age doubled will match his sister's age. hence 2(x+4)=3x+4
2x+8=3x+4
4=x
x is the age of ahmed three years ago. hence, now ahmed is 7 years old.
