The diameter of a sphere is 6 cm. What is the volume of the sphere?
A-87 cm
B -367 cm
C-1447 cm
D-2887 cm

f(x) = y

f(-3) = -5

step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
