Answer:
[tex] \sf{b. \frac{x}{2} <3}[/tex]
step by step explanation:
We will try one by one.
A. x + 5 < 3
Step 1. Subtitution Value of x
= 4 + 5 < 3
Step 2. Add by 4 with 5
= 9 < 5
A is wrong because 9 is bigger then 5
B. x/2 < 3
= 4/2 < 3
= 2 < 3
is true because 2 is smaller than 3
C. 9x > 36
9(4) > 36
36 > 36
is wrong, should 36 = 36
D. 18 < 8
is wrong because 18 is bigger than 8
