Answer: x=30
Step-by-step explanation:
Set them all equal to 180
so it would be 180=x+2x-1+3x+1
isolate x by adding or subtracting the 1
180=6x
x=30
Answer:
2 33/50
Step-by-step explanation:
Look at the decimal place. It is in hundreths. So, the decimal itself is 2 66/100. However, once you simplify it, the answer becomes 2 33/50.

Answer as a fraction = 1/720
Answer in decimal form (approximate) = 0.001388
Answer in percent form (approximate) = 0.1388%
========================================================
Explanation:
Let A = 1 to indicate the number of ways to get the names to line up in alphabetical order.
There are B = 6*5*4*3*2*1 = 720 different ways to arrange the six people. Notice how I started at 6 and counted my way down to 1, multiplying all along the way. This can be shortened to factorial notation to say 6! = 720. Or you could use the nPr permutation formula to get the same result (use n = 6 and r = 6).
Once you have the values of A and B, we form the fraction A/B = 1/720 which is the probability of getting the names in alphabetical order.
If you need the answer in decimal form, then use your calculator to find
1/720 = 0.001388
which converts over to 0.1388%
