How many odd integers are there between 101 and 999 have distinct digits?
guapka [62]
Every number will have only 3 digits. In the ones place, there are 5 choices. For every choice of digit made in the ones place, there are 8 possible choices for the hundreds place (you can choose from 1-9, omitting whatever is used in the ones place), and there are 8 possible choices for the tens place (you can choose from 0-9, omitting whatever has already been used elsewhere).

So there are 7\cdot8\cdot8=320 such numbers.

What is the solution of x + y = 2 and 2x + 5y = 16?
elena55 [62]
Multiply the first equation by two to get 2x + 2y = 4. 
Subtract the second equation from the first equation to get -3y = -12

y = 4. 

Plug y back in to get x = -2.
