Answer:
The family bought 2 bags of chips
Step-by-step explanation:
Let the number of chips bags be = x
The number of candy bars = twice as much as the number of bags of chip
The number of candy bars = 2x
The total cost spent is = $5.50
Therefore cost of all the chips bags + candy bars = 5.50
2x + x = 5.50
3x = 5.50
x = 
x = 1.83
x = 2 (approx)
Thus the number of chips is 2 and the candy bars is 2(2) = 4 bags
Answer:

Answer: B; -3x+3y=6
Step-by-step explanation:
When you put -3x+3y=6 and x-y=-2 in slope intercept form, you get the same equation. Which is y=x+2. Therefore the equations are graphed on the same line and share infinitely many solutions and are consistent as well as independent.
