X/3 = x + 2/5....multiply everything by common denominator of 15
5x = 15x + 6
5x - 15x = 6
-10x = 6
x = -6/10 reduces to - 3/5
or...
x/3 is the same as 1/3x
1/3x = x + 2/5
1/3x - x = 2/5
1/3x - 3/3x = 2/5
-2/3x = 2/5
x = 2/5 * -3/2
x = - 6/10 which reduces to - 3/5
The missing fraction is -1/12
Conjugate of (a - bi) is (a + bi).
Just change the sign on the imaginary part.
7 + 2i
Answer:
n = 2
Step-by-step explanation:

tan 45° = 1
then
sin 30° : tan 45° = 1 : n
½ : 1 = 1 : n
n = 2
