100 x 0.4 = 40. So 40 students listen to hip hop
Answer:
21 + 12i
Step-by-step explanation:
Given
(3 - 4i)(1 + 5i) - (2 - i) expand the product of factors
= 3 + 11i - 20i² - 2 + i
= 3 + 11i + 20 - 2 + i collect like terms
= 21 + 12i
8/12 and 4/6 and10/15 and20/30 and 40/60
2 X { 6 + [ 12 divided ( 3 + 1 ) ] } - 1
3 + 1 = 4
12 divided by 4 is 3
2 X { 6 + [ 3 ] } - 1
6 + 3 = 9
2 X { 9 } - 1
9 X 2 = 18
18 - 1 = 17!
