4 more than 15 is 4 + 15 = 19.
15 more than -3 = 12
It is composite because it has more than 2 factors
15 + 2/3 n = 30n = 3/2 x (30 - 15) = 22.5 or 221/2
5/15, is lower than 1/2 since 1/2 of 15 is 7/15.
a + 2
10/15 2/3 = 10/15 10/15 = 3/5
yes
4 more than 15 is 4 + 15 = 19.
It is composite because it has more than 2 factors
15 + 2/3 n = 30n = 3/2 x (30 - 15) = 22.5 or 221/2
