Sandy bought enough powdered juice mix to make 7 1/2 gallons of juice. if her kids go through 1 1/4 gallons of juice per week, how many weeks of juice did she buy?

6 weeks

Step-by-step explanation:

first you convert the fractions to make the demonstrator both equal 4 so,         7 1/2 = 7 2/4. now you divide 7 2/4 and 1 1/4 which should give you, 6 weeks

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
