Answer:
-15/2
Step-by-step explanation:
The next step would be to distribute the negative two through the parenthesis,
-2n-6=9
then you add the six, -2n= 15
then you divide by 15 by negative 2 and get -15/2
The answer is 40
you just times 23 by the number of photocopies you need with is 20
so 23x20 which is 460
500-460 is 40
1st is 19
2nd is 23
3rd is 27
4th is 31
5th is 35
6th is 39
7th is 43
8th is 47
9th is 51
10th is 55
This is because you are adding 4 each time, the rule of the sequence is 4n+15
