If a person invested half of her money at 9% and half at 7% and received $160 interest, find the total amount of money invested.

mr Goodwill [35]

Answer:

0.09(x/2) + 0.07(x/2) = 160

multiply each side by 2 to cancel the denominators:

0.09x + 0.07x = 320

0.16x = 320

Find the quotient and express it in the simplest form

pychu [463]

2i(4+5i)(4-5i) =82i
4+i nothing more can be done it is at simplest form

so $\frac{82i}{4+i}$ = $\frac{82}{17} + \frac{328}{17} i$

so your answer is $\frac{82}{17} + \frac{328}{17} i$

2(n+5)=-2 <br><br> I need the steps

Eva8 [605]

Answer:

n = -6

Step-by-step explanation:

2 ( n + 5 ) = -2

First, solve the brackets.

2n + 10 = -2

Now take 10 to the right side.

2n + 10 -10 = -2 - 10

2n = -12

Then divide both sides by 2.

$\frac{2n}{2} =\frac{-12}{2}$

And now you'll the value of n.

n = ( -6 )
