Can some one me with this math problem?

// I don't know what I am supposed to do. But looking the equation, I think we solve for t. But again, I am not sure.

3t - 321 lb = lb

First, add 321 on both sides.
3t = 321 lb.

Divide both side by 3.
t = 107 lbs.

3t - 321 lb. = 107 lb.

//Hope this helps

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
