Answer:

Problem 4: x = -11

Problem 5: x = -7

Step-by-step explanation:

<u>Problem 4:</u>

x + 51 + 60 + 80 = 180

x + 51 + 60 + 80 - 51 - 60 - 80 = 180 - 51 - 60 - 80

x = -11

Answer: x = -11

45 + 52 + x + 90 - 90 - 52 - 45 = 180 - 90 - 52 - 45

x = -7

Answer:

The median is 36.8

Step-by-step explanation:

The median is the middle number in an ordered list.

We have to sort the list in increasing or decreasing order

$5.9, 11.2, 13.9, 16.6, 22.9, 36.8, 43.1, 43.7, 44.2, 45.1, 49\\$

Now we can remove the first and last numbers in each iteration until we get to the median

$11.2, 13.9, 16.6, 22.9, 36.8, 43.1, 43.7, 44.2, 45.1\\13.9, 16.6, 22.9,36.8, 43.1, 43.7, 44.2\\16.6, 22.9, 36.8,43.1, 43.7\\22.9, 36.8, 43.1$

$36.8$
