One number is six less than the other. If their sum is 42, what are the two numbers?

Hi! I'm happy to help!

To find this answer, we first need to find what half of 42 is, so we can base our numbers off of that:

42÷2=21

To the number that is six less than the other and still equal 42, we need to get  our two numbers, one half of six higher than 21, and one half of six less than 21.

21+6/2=

21+3=

24

21-6/2

21-3

18

So, our two numbers are 24 and 18. They add together to equal 42, and 18 is 6 less than 18.

Step-by-step explanation:

A positive parabola is one that has a + sign out front or no sign at all (and the positive is understood).  A positive parabola opens like a cup with a bottom.  Therefore, the positive parabola has a min value.  A negative parabola opens upside down, like a mountain with a peak.  Therefore, the negative parabola has a max value.
