For this case we have the following system of equations:

To solve, we add both equations:

We find the value of "x":

The solution is (-4,10)
ANswer:
Option C
Answer:
Step-by-step explanation:
we have to find out the circumference of the pool
C=2*3.14*r
d=36, r=18
C=2*3.14*18=113.04 ft
The answer is B
If you move the decimal to two digits to the right, you will get 98.345.
Answer:
y = 6
Step-by-step explanation:
7x - 9y = 23
7(11) - 9y = 23
77 - 9y = 23 (subtract 77 from both sides)
-9y = -54 (divide both sides by -9)
y = 6
