Answer:
(0,-3)
Step-by-step explanation:
2x-y = 3
x+2y = -6
Multiply the first equation by 2 so we can eliminate y
2(2x-y =3)
4x -2y = 6
Add this to the second equation
4x -2y = 6
x+2y = -6
-----------------
5x +0y = 0
x = 0
Now find t
x+2y = -6
0+2y = -6
2y =-6
Divide by 2
y = -3
Divide 28 by 4 so that number is 1 week because 28/4 is 7 and there is 7 days in a week
From the last time i did it, i believe its B
182 / 8 = 22.25
you have to round up to account for the .75, so the answer is 23
