So elimination method is basically adding the equations and canceling out variables. 
-6x + 6y = 6
-6x + 3y = -12
The eaiest way to solve is by multiplying the bottom equation by -1.
-6x + 6y = 6
 6x - 3y = 12
Now you add the eqautions.
3y = 18
Divde 3 from both sides.
y = 6
Now plug in 6 into any of the original two equations. Lets use the first one.
-6x + 6(6) = 6
-6x + 36 = 6
Subtract 36 from both sides.
-6x = -30
Divide -6 from both sides.
x = 5
So your solution is (5, 6).
I hope this helps love! :)

Bill measures the circumference of a circular fish pond to be 28 ft. What is the diameter of the fish pond, rounded to the neare
zalisa [80]
It would be 9 ft. using the knowledge of \pi times the diameter (\pi equals aprox. 3.14) equal the circumference of a circle, and since we know the circumference, we need to divide that by \pi to get the diameter.

equation:  28/3.14=8.913 
                 rounding that would bring it to 9 ft.

Alexxandr [17]

Answer:

W=2

Step-by-step explanation:

First you have to fill A in as 19 because thats how many culinary recipes that she will need to know

Second you then have to get the variable W by itself so you would subtract 17 from the side that W is on

Once you subtract 17 from one side you have to subtract from the other

So therefore W would =2
