Answer:  27/14

Step-by-step explanation:

(x+2)/x +(x-6)/3x = (2x+9)/5x      

(3x+6)/3x + (x-6)/3x = (2x+9)/5x       First term:  [(x+2)/x]*(3/3) = (3x+6)/3x

(4x)/3x = (2x+9)/5x                             Combine (3x+6)/3x + (x-6)/3x  [=(4x)/3x]

(4/3)*5x = 2x + 9                      [(4x)/3x = 4/3] and multiply both sides by 5x

(20/3)x - 9 = 2x                     [(4/3)*5x] = (20/3)x;   Subtract 9 from both sides

20x - 27 = 6x                Multiply both sides by 3

14x = 27                          Simplify

x = 27/14                          And solve

If $396 is invested at an interest rate of 13% per year and is compound continuously, how much will the investment be worth in 3
Sveta_85 [38]

Answer:

The investment at the end of the period will be $584.89.

Step-by-step explanation:

FV = PV e⁽ⁿˣ⁾

FV = Future Value = ?

PV = Present Value = $396

n = Interest Rate = 13%

x = time in years = 3

e = mathematical constant = 2.7183

FV = 396 x 2.7183⁽⁰°¹³ ˣ ³⁾

FV = 396 x 1.4770

FV = $584.89

How to convert 750 in ^3 to yd^3
____ [38]

\bf \stackrel{\textit{we know that }}{1yd=36in}\implies \stackrel{\textit{therefore}}{(1yd)^3=(36in)^3}\implies \stackrel{\textit{distributing the exponent}}{1^3yd^3=36^3in^3}\\\\\\1yd^3=46656in^3~\hspace{8em}therefore\\\\\\750 \underline{in^3} \cdot \cfrac{1yd^3}{46656 \underline{in^3}}\implies \cfrac{750 yd^3}{46656}\implies \cfrac{125 yd^3}{7776}~~~~\approx~~~~ 0.016075~yd^3

Which table represents a linear function?​
Romashka-Z-Leto [24]

Answer:

1st one

Step-by-step explanation:

Since the x's for each one are going up by the same number, you are looking for a column of y's to either by going up by the same number or down by the same number.

The first table has a column of y's that look like this:  1/2 , 1 , 1  1/2,  2  

This is actually going up for 1/2 each time.

This table shows a linear function.
