The absolute value of a number is its distance from zero on the number line, regardless of its sign. In this case, the absolute value of 12 is simply 12, as 12 units away from zero in the positive direction.

5h means five times h - the times symbol is not written as it can be confused with a letter 'x': h = 12 → 5h - 2 = 5 x 12 - 2 = 60 - 2 = 58
When h has the value of 4, you substitute 4 for h in the expression 16-3h. This gives you 16 - 3(4), which simplifies to 16 - 12. Finally, the answer is 4.
Five molecules of hydrogen have 10 atoms.
