Step-by-step explanation:
4×10×2=80
20×10×1=200
20×8×1=160
20×10×1=200
2×20×1=40
10×2×2=40
80+200+160+200+40+40=720
She bought 7 paintbrushes

Answer is parallel lines
Reason - same slope (3x) and different y intercept means they will be parallel lines because their slope is the same but they will cross the y axis at different points.
I changed the first equation to y intercept form
y = 3x - 10 to match the other equation
y = 3x - 6
The answer is probably x=3. I am great at math so it should be the answer!
