7x-4x=27
Combine like terms 7x-4x (7-4) = 3
3x= 27
Divide by 3 on both sides to get x by itself

3x/3=27/3
Now what’s 3 divided by 3? 1 so x
And 27 divided by 3? 9
Answer:
X=9

if that's the case of this question it should go like this:

9(rooms)×5(monsters per room)= 45 monsters

30(monsters):5(monsters per room)=6 rooms

13(rooms)×5(monsters per room)=65 monsters

35(monsters):5(monsters per room)=7 rooms

At 7:00 am, the temperature was -4℉. At 9:00 am, it was 8° warmer. What was the temperature at 9:00 am? *
Nana76 [90]

<em>4℉.</em>

What we know about Degrees is that there is a<em> </em><u><em>Positive</em></u> type and a <u><em>negative</em></u> type.

(i.e: 30℉ is <u><em>positive</em></u> and -30℉ is <u><em>negative</em></u>.)

If the temperature was -4℉ at 7AM, then it is negative. If it goes up by an amount that is more than 4 then that negative will go up to a positive temperature. In this case: At 9AM it was 8° <u><em>warmer</em></u>.

<u><em>Warmer</em></u><em> is a </em><u><em>keyword</em></u><u>.</u> If it is warmer by an amount, Negative temperatures <u><em>will go up to a positive</em></u> and positive temperature <u><em>will just go up</em></u>. If it gets cooler, negative temperatures <u><em>will go down further</em></u> and positive temperatures <u><em>will go down to a negative</em></u>.

So lets work out this problem with our newfound knowledge.

-4° F at 7AM

8°  warmer at 9AM

-4 + 8 = 4.

<em>The temperature was 4°  at 9AM.</em>
