Step-by-step explanation:
No this is the awnser-3x+y=2
No
it is irrational for that reason - it goes on without bound
By factorizing, we have
![x^2 + 5xy - 6y^2 = (x - y) (x + 6y) = 0](https://tex.z-dn.net/?f=x%5E2%20%2B%205xy%20-%206y%5E2%20%3D%20%28x%20-%20y%29%20%28x%20%2B%206y%29%20%3D%200)
so that
![x - y = 0 \implies \boxed{y = x}](https://tex.z-dn.net/?f=x%20-%20y%20%3D%200%20%5Cimplies%20%5Cboxed%7By%20%3D%20x%7D)
or
![x + 6y = 0 \implies \boxed{y = -\dfrac x6}](https://tex.z-dn.net/?f=x%20%2B%206y%20%3D%200%20%5Cimplies%20%5Cboxed%7By%20%3D%20-%5Cdfrac%20x6%7D)
There are 180 boys in the school.
40% of the students are girls.
120/40 = x/60
multiply 120 by 60
divide 7200 by 40
