The variable y is directly proportional to the variable x. if y = 10 when x = 6, what is the value of y when x = 15? a) 20.5 b) 25 c) 30 d) 35

The answer is B

Step-by-step explanation:

The Least Common Multiple of 10 and 6 is 2 so you divide 10 by 2, which is 5, and divide 6 by 2, which is 3. you subtract 3 from 5 which is 2. this means that  in order to get 3 for x you got to divide 15 by 5 which is 3. This means you multiply 5 by 5 which is 25.

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
