Question

Can you help me i really don't understand math at all......

Answer 1

Answer:

C i think sorry if I'm wrong

Answer 2

Answer:

C) r ≥ s

Step-by-step explanation:

We are given that the variable r equals 12.5 and the variable s equals |-13|. We can use the process of elimination to help narrow down the answer choices. For those who don't know, the lines on the side of -13 mean that the number should be made positive, so in this case, -13 becomes 13. I'll give an example. Say if we are given the number |9|. DON'T change the number from a positive to a negative. The "|#|" is the make a number positive, not to make the number opposite of itself. The question asks for which of the inequalities is not true. We can all agree that r ≠ s (≠ is a not equal sign; 12.5 ≠ |-13|) so we can automatically eliminate it. r being less than s (r < s; 12.5 < |-13|) is also true so we can eliminate it, too. Now we are left with options C and D. For those who don't know this yet, ≥ means greater than or equal to and ≤ means less than or equal to. If we look back on option B, r is less than s and it's claimed that this statement is true so if we compare it to options C and D, D seems to go along with B so we can eliminate option D. Therefore, our only option left is C which is the correct answer. r IS NOT greater than s because how can 12.5 be greater than |-13| (remember the "|#|" means to make a number positive ONLY)? I hope this helps and please let me know if I am wrong! :D
