Is d = 5 a solution to the inequality below?

Question

60 d ≤ 57

Answer 1

LeeOnnah,

Another way to phrase the idea of whether or not something is a solution, is, "Will this inequality be TRUE if I substitute the given information?"

If it's true then it's a solution.

If it's false it is not a solution.

So, to decide if d= 5 is a solution, we need to substitute it into the original inequality:

60 d ≤ 57

60 (5) ≤ 57

300 ≤ 57

I have been doing math forever, and I STILL look at inqualities as, "the alligator eats the bigger number" LOL.

With

300 ≤ 57 , is the alligator mouth eating the bigger number, or are the two numbers equal? (I have to take into account that equal sign under the alligator too)

No. 57 is NOT greater than or equal to 300. That means this statement is FALSE, so d = 5 must NOT be a solution.

I see that you also asked another question similar to this one. Hopefully, this process helps you answer that one too.
