Answer:
Step-by-step explanation:
1. 0.4y = x is a direct proportion. It'd be more appropriate to write this as
y = x / 0.4, or y = 2.5x, in which case 2.5 is the constant of proportionality.
2. x = 1 - 2y is not a direct proportion because of the offset (1). A line representing a direct proportion must go through the origin (0, 0); this particular line does not do that.
Can you explain the question a bit more ??

Answer:
C. 1 day
Step-by-step explanation:
Chris:
10 - 4d
Evan:
8 - 2d
How many days will it take before they both have the same number of bags remaining?
Equate both expressions and solve
10 - 4d = 8 - 2d
Collect like terms
10 - 8 = -2d + 4d
2 = 2d
Divide both sides by 2
d = 2/2
= 1
d = 1 day
It will take 1 day before they both have the same number of bags remaining
