<h3>Answers: 48 and 72</h3>

=========================================================

Explanation:

The number 12 is a multiple of 3 because 3*4 = 12.

So when looking for common multiples of 3 and 12, we simply need to look at multiples of 12.

The multiples of 12 are:

  • 12, 24, 36, 48, 60, 72, 84, 96, 120, ...

We see that 48 and 72 are on the list. The values 21, 27, 63, 81 are not on the list, so cross them out.

Now we could keep that list of multiples going to see if 844 is on there or not. A better method is to divide 844 over 12. If we get a whole number, then it's a multiple of 12.

844/12 = 70.333 approximately.

This shows that 844 is <u>not</u> a multiple of 12. So we cross 844 from the list.

Only 48 and 72 are multiples of 12 (and also multiples of 3).

pogonyaev

Answer:

x=22

Step-by-step explanation:

According to the Alternate Interior angles theorem, the bottom left angle and the upper right angle have the same measure. Because they were formed from a pair of parallel lines crossed by a transversal one.

So, algebraically:

5x+5=115\\ 5x+5-5=115-5\\ 5x=110\\ \frac{5x}{5}=\frac{115}{5}\\x=22

5.
Paraphin [41]

Step-by-step explanation:

the mean value is the sum of all values divided by how many values there are.

so,

(3 + -5 + 70 + -90 + -13) / 5 = -35/5 = -7

-7° F is the mean temperature of the 5 cities.
