Steven has 14 steel balls of equal weight. if he puts 9 of them in one pan of a pan balance and the rest along with a weight of 20 grams in the other pan, the pans balance each other. what is the weight of one steel ball? a) 5 grams b) 14 grams c) 20 grams d) 0.65 grams

b = 5 grams

Step-by-step explanation:

Let b represent the weight of one ball.

Then 9b = 20 grams + 5b.

Solving for b, subtract 5b from both sides, obtaining 4b = 20 grams.

Then b = the weight of one steel ball = 5 grams.

Check:  Does 9(5 grams) = 20 grams + 5(5 grams)?

              Does 45 grams = 45 grams?  YES
