Step-by-step explanation:
ist you have to lind the lcd of each fraction. that would be 10.
1/2x5/5=5/10 of the boys have brown eyes
1/5x2/2=2/10 of the boys have blue eyes
3/10=3/10 of the boys have hazel eyes
The question is asking to see how many more boys have brown eyes than hazel eyes.
Subtract 3/10 from 5/10
and that gives you 2/10
5x^2 + x - 2= 0
Use the quadratic formula:-
x = [ -1 +/- sqrt(1^2 - 4*5*-2)] / 2*5
= -1 +/- sqrt 41 / 10
= -0.1 + 0.64 , -0.1 - 0.64
= 0.54, -0.74 Answer
