Answer:

7

Step-by-step explanation:

Basically what you do is simple. First your -10 turns into positive 10 and you add 10 to 25. Which gives you 35. Then you have 5x. With 5x you simply divide 35 by 5 which gives you 7.

Citrus2011 [14]

Answer:

8 : 24 P.M

Step-by-step explanation:

Data provided in the question:

On December 1 bright star Procyon will just be rising on the eastern horizon at 10 P.M

Now,

we know that Stars rise 4 minutes earlier each night

Therefore,

24 days later i.e after 24 nights the total early time

= 24 days × 4 minutes per day

= 96 minutes

or

= 1 hour 36 minutes early

Hence,

on Christmas Day the star will rise at 1 hour 36 minutes early than 10 P.M

= 8 : 24 P.M

What is the relationship between the magic constant (the sum of each row) and the sum of all the numbers in the square? Why does
NARA [144]

Let's say each row sums to 15

If we had 3 rows, then the total sum would be 3*15 = 45

If we added all of the values in the 3x3 magic square, then we'd get 45 as well.

This is one example showing that

sum of all values = (number of rows)*(magic constant)

You can replace "rows" with columns to get the same idea, because each column also adds to the same magic constant. The diagonals are an exception since we only have two of them.
