Question

If y varies directly as x, and y is 6 when x is 72, what is the value of y when x is 8?


1/9
2/3
54
96

Answer 1

Answer:

2/3

Step-by-step explanation:

you can set it up as x/y because it varies directly

so when y=6 x=72

72/6 = 12

so x will always be 12 times greater than y

x=12y

so if x=8

8=12y

y=8/12

y=2/3
