<h2>Answer:</h2>

Result = 2/5

Step-by-step explanation:

Question: Subtract to sum of (3/5 + 1/5i) and (4/5 - 2/5i) from (9/5 - 1/5i).

First we will take sum of  (3/5 + 1/5i) and (4/5 - 2/5i):

(3/5 + 1/5i) + (4/5 - 2/5i)

= 3/5 + 1/5i + 4/5 - 2/5i

= 3/5 + 4/5) + (1/5i - 2/5i)

= (7/5 - 1/5i)

Now subtract (7/5 - 1/5i) from (9/5 - 1/5i).

(9/5 - 1/5i) - (7/5 - 1/5i)

= 9/5 - 1/5i - 7/5 -1/5i

=  (9/5 - 7/5) - (1/5i + 1/5i)

= (2/5) - 0

= 2/5

                                   Result = 2/5

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.

Nicolas has $650 to deposit into two different savings accounts. • Nicolas will deposit $400 into Account I, which earns 3.5% an
Alinara [238K]
C) $694.25

Why?
Because you want to times the interest by 2 (1 is for one year but u want to find the amount after two years) then you multiply the amount given to each bank separately so:

400*0.07 (7% which is 7/100) = 28
250*0.065 (6.5% which is 65/1000) = 16.25

Then u add the interests together:
28+16.25 = 44.25

Finally you add that to the amount you started with:
$650+$44.25= $694.25

Javier drove 45 miles. This represent 60% of his entire trip. What is the total number of miles in Javier’s trip
Andrews [41]
60% of trip = 45 miles

let total trip distance = l

60% is given by multiplying by 0.6

So;

0.6l = 45 \\ \\ l = \frac{45}{0.6} \\ \\ \boxed{l = 75}

Your answer is 75 miles

(15/8+2/5)+(-7/8) show ur work
stepan [7]
The answer is 7/5 th. You can add fractions without first having a common denominator so you would change the 8's by multiplying it by 5 to get 40 and you would multiply the 5 by 8 to get 40 as well. And the rule whatever you do to the bottom you have to do to the top so whatever you multiplied 8 by do the same for the numerator and whatever you multiplied 5 by you do the same for the numerator. So your new equation would be (75/40+16/40)+(-35/40). you would then add the numerator's across to get 56 and the denominator would stay the same so the answer is 56/40. But you have to now simplify 56/40 down to 14/10 and then once more to 7/5 which is the final answer.
