HELP!Which property was used to rewrite the equation 2^x − 7 = 1 as 2^x = 8 ? A. Addition Property of Equality
B. Commutative Property
C. Multiplicative Inverse
D. Substitution Property of Equality

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

The key is the word about, they want an estimation.63 is closer to 60, 71 is closer to 7060 + 70 = 130ryan counted about 130 birds

Yes she is correct. when you do 1/5 the tbe is their to represent the fraction. so yes, kathy got it
