Answer:
-17 =s
Step-by-step explanation:
-8s +4 = -7s +21
Add 8s to each side
-8s+8s +4 = -7s+8s +21
4 = s+21
Subtract 21 from each side
4-21 = s+21-21
-17 =s
Answer:

Step-by-step explanation:
Because if it the cost of each your mulitplying and because you wanting to just define the variable p for pen and n for notebook all a variable is a letter than let you know what something is for using in math later
Mean: The average or the center of the value. To find this, you add up all the numbers and divide by how many numbers there are.
Example: 3, 4, 5
3+4+5 = 12.
There are 3 numbers.
12/3 = 4. The mean is 4
Median: Median means the middle value. You place the numbers in order and locate the middle value.
Example: 5, 4, 3 -> 3,/ 4,/ 5. Middle number 4.
Mode: Place the numbers in order then count how much each number appears. The number that appears the most repeatedly would be the mode.
Example: 3, 4, 4, 4, 5, 5.
The mode would be 4.
Range: Locate the highest and the lowest values of the given set and subtract the smallest to the largest.
