A car dealership has 75 cars and vans for sale. there are 21 more vans than cars. which system of equations can be used to find the number of cars(X) and the number of vans(Y) at the dealership? A. x+y=75 and y-x=21
B. x+y=96 and x-y=21
C. x+y=96 and x-y=21
D. x+y=75 and x-y=21

Dcups i think

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
