You have to subtract 8 from the left and then 8 from the right. If you do that then you'll have 5x=15. 
Then you divide "x" by 5 and 15 by 5.
X=3

Subtract the 8 from both sides and you’d have 15 then divide the 5x from both sides and x=3

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 )

Assuming that one-pint is equal to 473 ml, how many pints can be found in 3 liters?
Svetlanka [38]
Given that 1 pint is equal to 437 ml
and 1000 ml=1 liter
then
1 pint =(437/1000) liters
simplifying we get:
1 pint= 0.437 liters
thus amount of pints in 4 liters will be:
4/0.473
=8.45666586
~8.5 pints
