Combine like terms, showing one step per line. Justify each step using a rule of algebra or "Combining Like Terms." You may need to add extra rows. Expression Justification 7x + 3 + 9x + 15 Given 7x

By combining like terms, we have 16x + 18

Step-by-step explanation:

Here, we want to combine like terms

we simply bring terms that are similar together in this case

Thus, we have

7x + 9x + 3 + 15

16x + 18

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.
