let's call the denominator x and the numerador is 18 less then denominator, x - 18.
multiply
2.x = 5.(x - 18)
2x = 5x - 90
90 = 5x - 2x
90 = 3x
x = 90/3
x = 30
so:

Answer from: Quest
choice b
step-by-step explanation:
f(x) = 88x^2 -264x + 300
the line of symmetry of a parabola is defined by
h = -b/2a
where ax^2 +bx+c=0
so
h = - -264/ (2*88)
h = 3/2
so x = 1.5
