2__ = 2 + N + N = 16
14 = N + N
So the last two digits are equal to 14.

There are 5 numbers between 200 and 300 that the sum of their digits are equal to 16.
(x, y) = (0.5, 0.6)
oops sorry

V = a³
V = 5³ cm
V = 5 cm * 5 cm * 5 cm
V = 125 cm³
The coefficient of x^4 is 960x^4.
C. Negative
Add (1) + (2) (both equations) together and you get 2x + 2y + 2z = 42 (3). Multiply the equation (3) by 5 and you get 10x + 10y + 10z = 42 * 5 = ............... (diy).
Wait... Never mind, my hint is wrong, sorry.
Hint: The consecutive series of positive integers should be numbers that have divisors, e.g. 9 and 10 are consecutive, where 9 = 3 * 3 and 10 = 2 * 5.
