Guys i really really need help please help me with this assignment its due today -'_'-
Tasya [4]

Answer:

Monday: 5x + 14

Tuesday: Average is about 55.77 and Median is 56

Step-by-step explanation:

To combine like terms means to add or subtract the terms with similar variables. So I did as such to find the answer.

24 - 10 = 14 and 7x - 2x = 5x

The average is found by dividing the sum of all values in the list by the number of list options. The median is the value found in the middle of the list.
