Answer:
15
Step-by-step explanation:
Plug in 3 as x:
3x + 6
3(3) + 6
9 + 6
= 15
So, the simplified expression if x = 3 is 15
3:5 -> 6:10, 9:15, 12:20
8:10-> 4:5,16:20, 24:30
6:8 -> 3:4, 12:16, 30:40
6:18 -> 3:9, 12:36, 30:90
4:8 -> 1:2, 8:16, 12:24
8, 17/12 9, 9/24 10, 13/10 11, 11/10
2 ones and 8 hundredths
00.00
the first zero is tens, ones, and after the decimal, to the right is the tenths, hundredths and so on
