Question

the weight of a bag of golf balls varies directly as the number of golf balls in the bag.If a bag of 69 gold balls weighs 2,553 grams how many golf balls are in a bag that weighs 1,110 grams?​

Answer 1

Answer: 30

Explanation:

Given :The weight of a bag of golf balls varies directly as the number of golf balls in the bag.

Let x be the number of golf balls in a bag that weighs 1,110 grams.

Then we have the following direct variation equation,

`(x)/(1110)=(69)/(2553)`

Multiply 1110 both sides , we get

`x=(69)/(2553)*1110=30`

Hence, there are 30 balls in the bag.
