Answer:
5.414
Step-by-step explanation:
Formula to find circumference is 3.14 x 2r
So we can create a algebraic expression.
3.14 x 2r = 34 / 3.14 = 10.828 / 2 = 5.414
There will be 9 students left at the prep rally after 2 hours.
After 30 minutes
- Total Number of students = 729
- 2/3 of 729 = 486
- Number of students left = 729 - 486 = 243
After 1 hour:
- 2/3 of 243 = 162
- Number of students left = 243 - 162 = 81
After 1 hour 30 minutes :
- 2/3 of 81 = 54
- Number of students left = 81 - 54 = 27
After 2 hours :
- 2/3 of 27 = 18
- Number of students left = 27 - 18 = 9
Therefore, the Number of students left after 2 hours will be 9.

Answer:
35
Explanation:
Let x be equal to Elise’s number.
We can set up our equation like this:
(x-14)(-3)=-63
Expand the parentheses
-3x+42=-63
Subtract both sides by 42
-3x+42-42=-63-42
-3x=-105
Divide both sides by -3
-3x/-3=-105/-3
x=35
