After getting 5 new rocks, george gave half of his rock collection to susan. if george gave susan 36 rocks, which equation could be used to determine how many rocks george started with?                                        

Let x be the number of rocks that George have at first.

First, George have x rocks. Then, he gets 5 new rocks. So, we have:

Next, half of his rock collection is given to Susan.


Susan got 36 rocks, so the equation is

One shot. if 60% of 10 is 6, then what is 70%? we know it would be seven (since 60% is mathematically 60/100, or 6/10, then 70% is 70/100, or 7/10) but we can check anyway using ratios: 6 : 60% = x : 70%*inverse multiplicationx * 60% = 6 * 70%*divide both sides by 60%x = (6 * 70%) / 60%x = 7and since he has made 6 shots already, he would need just one more to get 7 shots or 70%. if the explanation is too confusing, comment and i will try to
