The simplest form can be 13/3: 7 or 4.3:7
Answer:
Step-by-step explanation:
3y = -x + 6
y = -1/3x + 2
y - 3 = -1/3(x + 1)
y - 3 = -1/3x - 1/3
y - 9/3 = -1/3x - 1/3
y = -1/3x + 8/3
1 week = 7 days
1 gallon = 16 cups ⇒ 1 cup = 1/16 gallon
1.5 cups = 1.5 · 1/16 gallon = 15 · 1/160 gallon = 3/32 gallon
1.5 cups per day = 3/32 gallons per day = 7 · 3/32 gallons per week
= 21/32 gallons per week
