A mathematical grammar question. Unsimplified answers allowed on GRID IN????????????

[RAlec114]

<ol>
<li> In a 5-digit number above, X and Y represent a single digit from 1 to 3, inclusive.</li>
</ol>

<p>What does “inclusive” mean? it reminds me of permutations and combinations, something I’ve always hated</p>

<hr>

<ol>
<li>
3x + 7y = y + 3x + 27, find y</li>
</ol>

<p>Guys…
I did:</p>

<p>7y = y + 27
6y = 27
y = 27/6</p>

<p>Now, it did not seem very obvious that 27/6 = 9/2.<br>
I gridded 27/6, but the answer key accepts 9/2 and 4.5</p>

<p>Will I really lose points for that? … :(</p>

<p>I don’t think you would lose points for not simplifying.</p>

<p>You don’t need to simplify.

A fraction does not have to be reduced unless it will not fit the grid. For example, 15/25 will not fit. You can grid 3/5, 6/10, or 9/15. The decimal form, .6, can also be gridded.

<p>Awesome! Ok. Stupid answer key didn’t mention that</p>

</p>

<p>“Inclusive” just means that the endpoints are part of the set. So, if I wanted you to list the “numbers from 100 to 103 inclusive,” you’d write “100, 101, 102, 103.” If I did not say “inclusive” (or if I specifically mention “non-inclusive”), your list would only be “101, 102.”</p>

<p>Just simplify it. Really.</p>
