Dmitry [639]

Answer:

Step-by-step explanation:

If first odd number is x

THen next consecutive odd number is x + 2

Next one is x + 4

Now, we can write the word problem as:

$x+x+2+x+4 \leq 33$

Now we solve:

$x+x+2+x+4 \leq 33\\3x+6 \leq 33\\3x \leq 27\\x \leq 9$

So, x is less than or equal to 9, so it can be

9, 7, 5 .....
