Answer:
?
Step-by-step explanation:
360 is going to be what you have to end up with. Add all of the numbers you have then subtract 360 and whatever you get that's your anserw
3x - y = 9
y = -2x + 11
3x - (-2x + 11) = 9
3x + 2x - 11 = 9
3x + 2x = 9 + 11
5x = 20
x = 20/5
x = 4
y = -2x + 11
y = -2(4) + 11
y = -8 + 11
y = 3
solution (where the lines intersect) is (4,3)
The answer is 1494.569444
