Answer:
18 + x or x + 18
Step-by-step explanation:
Hi there! I'm glad I was able to help you solve this math problem!
We are already given the number eighteen to start with, so this helps us a lot.
Since the word INCREASED means to add, and <u>we're increasing eighteen by x</u>, all you have to do is write it out to get your algebraic expression, as shown:
18 + x
You can also write the expression as x + 18! It doesn't matter what order you write it in.

It is the longest side of a right triangle.
Ryan is correct, the mean is about 8.1.
To find the mean, you have to add up all the values, then divide by the total amount.
For Sample A:
60 x 6 + 90 x 7 + 145 x 8 + 150 x 9 + 55 x 10 = 4050
If you add up all the adults, you have 500.
Dividing 4050 by 500 = 8.1
Sample B will produce a very similar result.
