Answer:

$m = 6$

Step-by-step explanation:

$\frac{15}{10} = \frac{m}{4}$

$15 \times 4 = 10m$

$60 = 10m$

$\frac{60}{10} = \frac{10m}{10}$

$6 = m$

Subject to some of (3/5 + 1/5i) and (4/5 - 2/5i) from (9/5 - 1/5i). the result is what

romanna [79]

The correct answer is: 2/5.

Explanation:

First you have to add the following expressions:

$(\frac{3}{5}+\frac{1}{5}i)+(\frac{4}{5}-\frac{2}{5}i) \\ (\frac{3}{5}+ \frac{4}{5})+(\frac{1}{5}i-\frac{2}{5}i) \\= \frac{7}{5}-\frac{1}{5}i$

Now subtract the above expression from $(\frac{9}{5}-\frac{1}{5}i)$ :

$(\frac{9}{5}- \frac{1}{5}i) - (\frac{7}{5} -\frac{1}{5}i) \\ (\frac{9}{5} -\frac{7}{5}) + (\frac{1}{5}i -\frac{1}{5}i) \\ \frac{2}{5} \\$

Hence the correct answer is 2/5.
