Calculate the simple interest on a loan of $3500 for a period of 6 months at a yearly rate of 5%. (10 POINTS!!)​
ser-zykov [4K]

Answer:

$3,799.20

Step-by-step explanation:

We presume your formula is intended to be ...

M = Pm(1 + m)^(na)/((1 + m)^(na) - 1)

where M is the monthly payment, m is the monthly interest rate, n is 12, and a is the number of years.

This formula gives written below:

M = 3500·(.08/12)·(1 + (.08/12))^(12·2)/((1 + (.08/12))^(12·2) -1) ≈ 158.30

The total payback will be the sum of 24 of these payments is written below;

payback = 24×$158.30 = $3,799.20

Sa se gaseasca numerele a si b a caror medie aritmetica este 200 si care sunt invers proportionale cu 8 si respectiv 4,5.
Olenka [21]
Bonjour, (as you write in roumain)

Soient a et b les 2 nombres

(a+b)/2=200==>a+b=400

8/a=4.5/b==>16b=9a

a+9a/16=400
==> 25a/16=400
==>a=400*16/25
==>a=256
et b= 9*256/16; b=144

Steps to sloving -2(x+3)=-10​
FromTheMoon [43]

Answer:

<h2>x = 2</h2>

Step-by-step explanation:

-2(x+3)=-10          <em>divide both sides by (-2)</em>

\dfrac{-2(x+3)}{-2}=\dfrac{-10}{-2}

x+3=5            <em>subtract 3 from both sides</em>

x+3-3=5-3

x=2
