The formula to solve:

(10 being the percent)


Therefore it had a 180% decrease.
X+y=90
x<2y
x+y< 3y
but x+y=90
90<3y
⇒ y>30
for example y=31, then x= 59
y=32, x= 58
.............................................
y=40, x=50
The value of x is -9 and 3.Option D.
Step-by-step explanation:
Given,

To find the value of x.
We will apply middle term factor formula.
The given equation can be written as,

or,
+(9-3)x-27 = 0
or, x²+9x-3x-27= 0
or, x(x+9)-3(x+9)=0
or, (x+9)(x-3) = 0
So, x = -9 and x = 3
Hence,
The correct option is Option D.
