Answer:
Infinitely many solutions
Step-by-step explanation:
Eq. 1 and eq. 2 are the same line.
Multiply eq. 2 by (-3) to get eq. 1.
Multiply eq. 2 by 3 and add to eq. 1 to eliminate x.
Consistent dependent system of equations, infinitely many solutions.
1.)1x-6y=-15
2.)-4+2y=5
Answer: $76.85
Your bill:
47 + (47 * 15%) = ?
47 + (7.05) = 54.05
Eliza's bill:
19 + (19 * 20%) = ?
19 + 3.8 = 22.8
22.8 + 54.05 = 76.85
110
200+20=220
220/2=110
10
2 + 5 = 7
3 + 5 = 8
4 + 5 = 9
5 + 5 = 10
12
