Answer:
22
Step-by-step explanation:
let the x be the number
8+4x=96
4x=96-8
4x=88
x=88/4
x=22
check: 8+4(22)=8+88=96
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
The first one is B. I'm sorry, but I don't know the other 2.
A
Hopefully I did the math right
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.
