Question

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

Answer 1

The answer is B

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.

Answer 2

B

Explanation:

10/6×15=25
