Step-by-step explanation:
I want to say answer (A)is the correct answer
Answer:x=40
Step-by-step explanation:
To find this
8 times the reciprocal of a number
We get
Assume the number is x
8×1/x=2×1/10
8/x=2/10
8/x=1/5
Cross multiply
x=40
The way I figured this one out was saying that if it takes 2lbs to stretch it to 12 inches and 5lbs to stretch to 18 inches that means that 3 additional pounds = 6 inches. Therefore, each additional pound is 2 inches. We know already that with 2 lbs it was 12 inches in length and we can also say that 2 lbs = 4 inches. So subtract 4 from 12 and you end up with the answer of 8 inches.
