<span>X+6y=1 x = -6y + 1
3x-10y=17 

replace </span>x = -6y + 1 into 3x-10y=17 

3x-10y=17 

3(-6y + 1) -10y=17 
-18y + 3 - 10y = 17
-28y = 17-3
-28y = 14
 y = 14/-28
y = -1/2

x = -6y + 1
x = -6(-1/2) + 1
x = 3 +1
x = 4

solutions x = 4 y = -1/2 or (4,-1/2)

The sum of three consecutive multiples of 9 is 567.<br> One of these multiples is
Dmitry_Shevchenko [17]
If three consecutive values add to 567 the middle value must be 567/3 = 189
Since the values are multiples of 9, the other values must be 189 - 9 and 189 + 9

The three values are 180, 189, 198

Solve the problem. A $8920 note is signed, for 160 days, at a discount rate of 6.5 % Find the proceeds.
GuDViN [60]
<h2>Hello!</h2>

The answer is $101688

<h2>Why?</h2>

Since there is not enough information about the rate, let's assume that it's a daily rate.

<h2>Calculations</h2>

Let's say:

P : Proceeds

o : original amount

d : number of days

r  : percentual rate

So,

P = o + o*(r*d)\\

Let's make the percentual rate (6,5%) a real number by dividing into 100,

\frac{6,5}{100}=0,065


By substituting, we have

P = $8920 + $8920*(0,065*160)= 8920 + 8920*10,4\\P= $8920 + $92768 = $101688

P = $101688

Have a nice day!
