A croquet ball weighs 460 grams. Together a golf ball and a croquet ball weigh the same as ll golf balls. What does the golf bal weigh?
I would be able to figure out the answer, but they're asking me to write the eqaution, and I always do it wrong!
Let C be the croquet ball's weight and G be the golf ball's weight.
Then C = 460gm and C + G = 11G
Can you substitute for C and solve for G?
