Write and solve an addition equation to find x.
perimeter = 48 ft
others= 20 & 12
equation= 20+12+x=48

20 + 12 + x = 48    / -20
12 + X = 48 - 20    / -12
X = 48 - 20 - 12
X = 28 - 12
X = 16

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
