Answer:the mean is 90
Step-by-step
you find the sum of the values then divide them by the amount of numbers in the set
-37 = <u>n
</u> 23
<u>
</u>to solve for n, undo what is happening to the n. if the n is being divided by 23 to get -37, then multiply both sides by 23 to figure out what n is.
<u>
</u>-37 * 23 = <u>n * 23
</u> 23
<u>
</u>-851 = n
Answer: CD=18
Explanation: Use the side-splitter theorem and solve.
1) (3/x)=(4.5/(x+6)), cross multiply and solve for x
2) 6x+36=9x
3) x=12
4) Solve for CD
5) (12)+6=18
