Answer:

Step-by-step explanation:

First choose the president. From the 4 people, everyone can be the president except Dan, so there are 3 choices.

Then, choose the treasurer. Neither Bob nor Dan can be the treasurer so there are only 2 choices.

Now choose the secretary. Cyd is the only person who can't take this position, so there are 3 choices.

We are asked by the number of ways of choosing the 3 officers. Using the product rule, this is equal to 3×2×3=18.

The sum of two numbers is 64 and their differences in 10. Find the numbers

uranmaximum [27]

Answer:

37 and 27

Step-by-step explanation:

Lets say that the two numbers are x and y. We get the equations x + y = 64 and x - y = 10. We can then add these two equations together to get, 2x = 74. Then we divide by two on both sides and get x = 37. We then plug this value back into the second equation and get that 37 - y = 10. We can simplify this and we get that y = 27. So our two numbers are 37 and 27.
