List the numbers: 2,7,9,16,25
----------------------------------------
If the 100th number in the list is x,what is the 103rd number in the list?
Good question.
-----------------------------------------
The sum of two numbers is 19.5 If 5 times the smaller number is 3 less than twice the larger number,what are the numbers?
----------------
Equations:
x + y = 19
5x = 2y-3
---------------
Rearrange:
x + y = 19
5x-2y = -3
---------------
5x + 5y = 95
5x - 2y = -3
---------------
7y = 98
y = 14
Then x = 5
