Answer:
2
Step-by-step explanation:
1,3,4 are arithmetic sequences
2 is a geometric sequence
Answer:
n > -14
Step-by-step explanation:
Firstly, you use the distributive property;
-12 - 6n > 72
Then, since 12 is negative, you add 12 to both sides;
-12 - 6n > 72
+12 +12
-6n > 84
Then you divide both sides by -6 to get n > -14.
Shoot, hold on; this is an edit; did you mean that 72 is greater than -6(2 + n) or did you accidentally flip the sign in the picture? Hopefully I did what you needed.
Answer and Explanation:
To find : Perform the indicated operations?
Solution :
Modular math is defined as

or 
Where, A is the dividend
B is the divisor
Q is the quotient
R is the remainder
The solution is 
Now, We perform same in every case
1) 
We can direct add the term,

Now, we divide 15 by 5 and see the remainder

Remainder is 0.
So, 
2) 
We can direct subtract the term,

Now, we divide -4 by 12 and see the remainder

Remainder is 8.
So, 
3) 
We can direct multiply the term,

Now, we divide 12 by 5 and see the remainder

Remainder is 2.
So, 
4) 
We can direct divide the term,

Now, we divide 0.5 by 5 and see the remainder

Remainder is 0.5.
So, 
1 day = 750 m
1 * 7 = 750 * 7
7 days = 5250 m
Now, since 1 km = 1000 m, this means in order to convert from meters to kilometers you must divide by 1000
5250 / 1000
= 5.25 km
Or, you could do the hard way by going to wolfram alpha / google and typing 5250 m to km.
Hope this helps!
