Answer:
If you meant median, the median would be the data in the middle.
Step-by-step explanation:
In this case, 1-2-3-4-5 (here) 6-7-8-9-10
5.5 would be in the middle because there is an even amount of numbers.
Answer:
x = 5.5
y = - 6.5
Step-by-step explanation:
Let one of the numbers = x
Let the other number = y
x + y = - 1
x = y + 12 Put the second equation into the first one
y + 12 + y = - 1 Subtract 12 from both sides
y + y = - 1 - 12 Combine both left and right sides
2y = - 13 Divide by 2
2y/2 = - 13/1
y = - 6.5
x + y = - 1
x - 6.5 = - 1 Add 6.5 to both sides
x = 5.5
Answer:
1. decreases

Answer: x = 3
Step-by-step explanation:
x+5 = 3x-1
+1 +1
x+6 = 3x
-x -x
6 = 2x
/2 /2
3 = x
