66 x 3 = 198
198 + 2 = 200
200 / 3
As an improper fraction, anyway. 66 2/3 is already *technically* a fraction.
The answer is $160. You have to subtract 200 from 20%
So?
-756*x +x =1 ?
-755 x = 1
x= -1/755
or
what two numbers when multiplied equal -756 but when added together equal 1?
numbers are x and y
x*y= -756
x+y=1
rearrange the 2nd eq
y=1-x
substitute
x(1-x)=-756
distribute
x-x^2=-756
solve for zero
x^2-x-756=0
factor/quadratic equation
V=(4/3)(pi)(r^3)
A=4(pi)(r^2)
36(pi)=4(pi)(r^2)
36=4(r^2)
9=(r^2)
r=3
V=(4/3)(pi)(3^3)
V=(4/3)(pi)(27)
V=36(pi)
