Answer:
Seth has 21 nickels
Step-by-step explanation:
Let n represent the number of nickels. Since Seth has 8 more nickels than dimes, then (n-8) is the number dimes.
Nickel is worth 5 cents and dime is worth 10 cents. Thus, n nickels are worth 5n cents and (n-8) dimes are worth 10(n-8) cents. The total value of Seth's coins is $2.35 that is 235 cents, then
![5n+10(n-8)=235.](https://tex.z-dn.net/?f=5n%2B10%28n-8%29%3D235.)
Solve this equation:
![5n+10n-80=235,\\ \\15n=235+80,\\ \\15n=315,\\ \\n=21.](https://tex.z-dn.net/?f=5n%2B10n-80%3D235%2C%5C%5C%20%5C%5C15n%3D235%2B80%2C%5C%5C%20%5C%5C15n%3D315%2C%5C%5C%20%5C%5Cn%3D21.)
Answer:
x=27
Step-by-step explanation:
180-2x-40+180-3x+180-x-50+180-4x = 360
360-2x-40-3x+360-x-50-4x= 360
360-10x-90= 0
10x= 270
x= 27

Complete Question
Stillwater Junior High divides students into teams taught by a group of teachers. The table shows the number of students in each team.
Team{Number of Students}
Acers{78}
Blazers{80}
Outbacks{83}
Quasars{77}
Voyagers{82}
<u>Total-400</u>
Answer:
(A)81/399
Step-by-step explanation:
The probability that the Principal selects a voyager on the first try is:
82/400
Since another student is to be selected, the <u>total population has reduced by 1 </u>and the <u>number of voyagers likewise has been reduced by 1.</u>
Therefore:
Probability that another voyager is selected on the second try =
81/399
<u>The correct option is A.</u>
