Answer:
dunt know just doing it for the points
Step-by-step explanation:
Um b is maybe 9n + 5 = 15n
um c is maybe 3 - 5 to the third power =3 - 125 = -122 + 7 = -115
maybe you have to add the positive 15n to -115 = -100n
um d is maybe 3b + 2c - 10c = 3b + -8c = -5 <span />
Answer:
<em>10 19/24, 4 9/16, 3 11/15</em>
Step-by-step explanation:
15. 15 4/24 - 4 9/24 = 10 19/24
13. 8 3/16 - 3 10/16 = 4 9/16
17. 6 5/15 - 2 9/15 = 3 11/15
