**Answer:**

10

**Step-by-step explanation:**

2 1/2 ÷ 1/4 reduce

5/2 × 4/1 = 20/2

20 ÷ 2 = 10 pounds of flour per sugar

(I'm not very good at math so this might be wrong)

This is just about substitution!! 9(5)-3(5), 3 • 5 = 15

9 • 5 = 45

so Now you have, 45 - 15 = 30

**Answer:**

40.9 - 5y ## ^ combine like-terms

**Answer:**

There are (63) combinations. The notation means "six choose three". Out of six items (flavors) choose three.

(nk)=n!k!(n−k)!.

(63)=6!3!3!.

Think of it this way. There are 6 ways to choose a flavor. Once you choose, there are 5 ways to choose the next. After that, there are 4 flavors left. which is 6!/3!=6⋅5⋅4⋅3⋅2⋅13⋅2⋅1=6⋅5⋅4=120.

But, you could have chosen {chocolate,vanilla,strawberry} and you get the same combination as {vanilla, strawberry, chocolate} so we have to divide by 3!=3⋅2⋅1=6 to account for the order of choosing.

So the number of combinations of flavors is (63)=1206=20.
