Let's tell and write the correct answers in the blank spaces. a) If N = {11, 12 ,13, 14), n (N) =
b) If S = {1, 4, 9, ... 49), n (S)
c) If V = {i}, subsets of V are
and its subset is
and
d)if A={teachers} and B={mathematics teachers},then universal set is and its subset is

a: 1/6, j: 1/4

step-by-step explanation: you are welcome

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

yes because they have the same amount of green and blur marbles.
