Which of the systems of equations below is equivalent to the system shown? 4x + 5y = 3
2x + 3y = 1
A. 4x + 5y = 3
−4x − 6y = 2
B. 12x + 15y = 9
−12x + 18y = 6
C. 4x + 5y = 3
−4x − 3y = 1
D. 12x + 15y = 9
−12x − 18y = −6

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
