Answer:
(4, -3)
Step-by-step explanation:
The system of equations can be described a number of ways. One possible description is "a consistent pair of linear equations in two variables."
Perhaps you want to know the solution to this system of equations. I find it easiest to graph them. The attached graph shows the solution to be ...
(x, y) = (4, -3)

You can also use "elimination" to simplify the system to a single equation in a single variable. Adding 4 times the second equation to 3 times the first will do that.
3(5x +4y) +4(2x -3y) = 3(8) +4(17)
23x = 92 . . . . . simplify
x = 4 . . . . . . . . divide by 23
Substituting this value into the first equation, we have ...
5(4) +4y = 8
5 +y = 2 . . . . . . divide by 4
y = -3 . . . . . . . . subtract 5
The solution is (x, y) = (4, -3).
N= pi
2nr=C
C=94.2
94.2/2=nr
47.1=nr
47.1/n=r
15=r
2r = D
2(15)=30
Your answer is 30 inches

Answer:
hi
Step-by-step explanation:
i mean like 5+4=9 9 divided by 2= 4.5
4.5 x 2 = 9 - 4 = 5
hope this helps
