   82n - 3/4=942
           +3/4  +3/4(.75)
    82n=942.75
    divide 82 by both sides
     n = 11.49 or 11.5

4n+78n-3/4=942
=> 82n - 3/4 = 942 
=> 82n = 942 + 3/4 (make them into like fractions ..same denominators)
=> 82n = 3771/4
=> n = 3771/ 4 *82
=> n = 3771/ 328

Hope it helps !!!

Use elimination to determine which ordered pair is the solution to the system of equations below. Use the space below to show al
lidiya [134]

Answer:

in the ordered pair; ( x  = 27/4 , y = 1/4 )

Step-by-step explanation:

Given that:

The system of the equation shown below is:

-2x - 14y = 10

 2x + 2y = 14

We are to use the elimination method to determine the ordered pair.

From the above equation:

-2x - 14y = 10  --- (1)

 2x + 2y = 14   --- (2)

Add both equation 1 and 2 together in order to eliminate x, then we can solve for y first.

-2x - 14y = 10

<u>  2x + 2y = 14       </u>

<u>  0  - 16y = -4        </u>

<u />

- 16 y = - 4

divide both sides by - 16, Then:

-16y /-16 = -4/-16

y = 1/4

Since y = 1/4, Then from equation (2), x will be :

2x + 2y = 14

2x + 2(1/4) = 14

2x + 1/2 = 14

2x = 14 - 1/2

2x = 13.5

x = 13.5/2

x = 27/4

Thus, in the ordered pair; ( x  = 27/4 , y = 1/4 )

Please someone help please pls
mario62 [17]

Answer:

h=h= \frac{5R^{3} }{LU}

Step-by-step explanation:

1.) You must isolate the h from the equation by dividing both sides by L (or multiply by its reciprocal, which in this case, the reciprocal on L is \frac{1}{L}    .....So it would look like:

(\frac{1}{L} )*\frac{5R^{3} }{U} = \frac{L}{h}* (\frac{1}{h} )\\

2.) Simplify the equation if you need to (in this case, its not needed)

\frac{5R^3}{LU} =h

That's your answer :)

Over the last three evenings, Diane received a total of 105 phone calls at the call center. The third evening, she received 4 ti
sergij07 [2.7K]

Answer:

Make an eqaution from here.
Let’s make evening 2 “x”

So the first evening has 9 less then the secon evening so…
x-9
Of course theres the second evening (x).

X-9+x
Then the third evening has 4 times as much as the second meeting so…
x-9+x+4x

And when solved, it has to equal 105.

So solve from here.
Combine like terms.

6x-9=105
Isolate

6x=114
x= 19

First evening is 9 less then 19, so 10.

The second evening was 19 calls.
The third evening was 4 times the second evening so, 19*4= 76

1st night = 10

2nd night= 19 calls
Thrid night= 76 calls
