The amount a spring will stretch varies directly with the amount of weight attached to the spring. if a spring stretches
2.1 inches when 80 pounds is attached, how far will it stretch when 40 pounds is attached?

The spring will stretch 1.05 inches.

Step-by-step explanation:

The amount a spring will stretch varies directly with the amount of weight attached to the spring.

Let the spring stretches x inches when 40 pound is attached.

we get the following relation;

=>

=>

x = 1.05 inches

Hence, the spring will stretch 1.05 inches.

answer:  

step-by-step explanation:

and 7 is odd because only 7 x 1 equals seveb
