It would help if you proofread your questions before you posted them. Instead of "2!/2", I assume you mean 21.2. I also assume that Ted wants a share. 21.2/6 = ?

prealgebra
1,000-320 = (2*20)x Solve for x.

I assume you have a typo somewhere, because the r's cancel each other out. -5r+6 ? -5r-10

Algebra 1
(65+67+67+93+6x)/10 = 70 (65+67+67+93+6x)/10 = 79 Solve for x in each case.

math
If you multiply 6x+5 time x-1, you will see that you are not doing it right. You need to split the 6 into its factors and pair the largest one with -5. I could give you the complete answer, but it is better that you find it for your self.

Here is the way to set up that problem. 171/19 = x/11 Then do what Kat said.

Online "^" is used to indicate an exponent, e.g., x^2 = x squared. The one without an exponent.

Right

Stats
Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportions/probabilities and their Z scores. Z = (score-mean)/SD

Math (oops)
I goofed. If median is 5 and range is 5, scores would range from 3 to 7. False.

You don't show your work or all of the data. What statistics are in Act Two? With all that missing, we cannot respond.

Math
Mean = (94.1-15)/60 Since every score is reduced by the same amount, the SD remains the same. SD = 24.23/60
