Answer:
Take 66 and subtract 10 to get 56
Divide 56 by 2 to get 28 - this is the first number.
Add 10 to 28 to get 38 - this is the second number.
Prove by adding 28 + 38 to get 66
Answer:

Step-by-step explanation:
Total flavors Sammy initially had = x
Number of flavors Sammy throw away = y
After throwing away y flavors, the number of flavors Sammy will be left with = x - y
He needs to make 10-flavor bags from these (x - y) flavors. In order words he needs to chose 10 flavors for each bag from(x - y) flavors. The order of selection is not important here, so this is a problem of combinations. Also since we have to make selections or small groups, this also indicates that we have to use combinations.
So we need to make combinations of 10 flavors from a total of (x - y) flavors. This can be represented as 
The formula for combinations is:

Using the values in this formula, we get:

The smallest 3 common multiples of 2 and 3 are 6, 12, and 18 .
The smallest 3 common multiples of 3 and 6 are also 6, 12, and 18 .
Answer:
Step-by-step explanation:
-13/-12 = 1.0833......
The number is non terminating and repeating. So, it is rational number
If they sold 89 calendars over 4 weeks, the 'equation' would look like (x = average calendars sold over 4 weeks):

If you solve it, you get:

Which is equal to
22.25. Hope this helps!
