Check all that apply. Distribute 9, by multiplication, to the variable, a, and to the constant, 8. Write the two multiplications, 9(a) + 9(8) The expression 9(a) is written as 9a. The expression 9(8) equals 72. The equivalent expression is 9a + 8. The equivalent expression is 9a + 72.

(-8,5) bu tun not sure ok

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
