ANSWER: 7/10
move the decimal once to the left. That will now be 7 over something. How did I get 10? Well, since you move it once only, add a decimal to the 1 because there's an invisible 1 under 0.7
There are 2,162,160 possible combination that could be made if there are 14 bands and only 6 slots available. This is computed using factorial. By using factorial we first need to identify the number of band and the number of slots available. It could be express as 14! - 8! or 14 x 13 x 12 x 11 x 10 x 9, which is equal to 2,162,160 combination.
The first square is 7.5

Answer:
Taco: $1.25
Burrito: $2.75
Step-by-step explanation:
Let x = tacos
y = burritos
Since the first family bought 2 burritos, we multiply y by 2; we multiply x by 3 since they bought 3 tacos.
3x + 2y = 9.25
We do basically the same thing for the other family
7x + 4y = 19.75
We'll use elimination method to solve this
7x + 4y = 19.75
3x + 2y = 9.25
Multiply the bottom equation by -2
7x + 4y = 19.75
(3x + 2y = 9.25)-2
7x + 4y = 19.75
-6x - 4y = -18.5
Now subtract the equations and we get this
x = 1.25
A taco costs $1.25
Plug the new x into one of the original equations
3(1.25) + 2y = 9.25
3.75 + 2y = 9.25
- 3.75 - 3.75
2y = 5.5
2y/2 = 5.5/2
y = 2.75
A burrito costs $2.75
