Answer:
![12\dfrac{7}{40}](https://tex.z-dn.net/?f=12%5Cdfrac%7B7%7D%7B40%7D)
Step-by-step explanation:
The given expression is
![\left(9\dfrac{7}{8} + 2\dfrac{4}{5}\right)-\dfrac{1}{2}](https://tex.z-dn.net/?f=%5Cleft%289%5Cdfrac%7B7%7D%7B8%7D%20%2B%202%5Cdfrac%7B4%7D%7B5%7D%5Cright%29-%5Cdfrac%7B1%7D%7B2%7D)
We need to find the simplified form of the given expression.
It can be rewritten as
![\left(9+\dfrac{7}{8} + 2+\dfrac{4}{5}\right)-\dfrac{1}{2}](https://tex.z-dn.net/?f=%5Cleft%289%2B%5Cdfrac%7B7%7D%7B8%7D%20%2B%202%2B%5Cdfrac%7B4%7D%7B5%7D%5Cright%29-%5Cdfrac%7B1%7D%7B2%7D)
Combine integers and fractions separately.
![(9+2)+(\dfrac{7}{8}+\dfrac{4}{5}-\dfrac{1}{2})](https://tex.z-dn.net/?f=%289%2B2%29%2B%28%5Cdfrac%7B7%7D%7B8%7D%2B%5Cdfrac%7B4%7D%7B5%7D-%5Cdfrac%7B1%7D%7B2%7D%29)
Taking LCM we get
![11+\dfrac{35+32-20}{40}](https://tex.z-dn.net/?f=11%2B%5Cdfrac%7B35%2B32-20%7D%7B40%7D)
![11+\dfrac{47}{40}](https://tex.z-dn.net/?f=11%2B%5Cdfrac%7B47%7D%7B40%7D)
In can be written as
![11+\dfrac{40+7}{40}](https://tex.z-dn.net/?f=11%2B%5Cdfrac%7B40%2B7%7D%7B40%7D)
![11+1+\dfrac{7}{40}](https://tex.z-dn.net/?f=11%2B1%2B%5Cdfrac%7B7%7D%7B40%7D)
![12+\dfrac{7}{40}](https://tex.z-dn.net/?f=12%2B%5Cdfrac%7B7%7D%7B40%7D)
![12\dfrac{7}{40}](https://tex.z-dn.net/?f=12%5Cdfrac%7B7%7D%7B40%7D)
Therefore, the expression
is equivalent to the given expression.
<h3>
<u>Explanation</u></h3>
- Given the system of equations.
![y = - \frac{1}{4} x - 2 \\ x = 4](https://tex.z-dn.net/?f=y%20%3D%20%20-%20%20%5Cfrac%7B1%7D%7B4%7D%20x%20-%202%20%20%5C%5C%20x%20%3D%204)
- Substitute x = 4 in the first equation.
![y = - \frac{1}{4} (4) - 2 \\ y = - 1 - 2 \\ y = - 3](https://tex.z-dn.net/?f=y%20%3D%20%20-%20%20%5Cfrac%7B1%7D%7B4%7D%20%284%29%20-%202%20%5C%5C%20y%20%3D%20%20-%201%20-%202%20%20%5C%5C%20y%20%3D%20%20-%203)
We have both x and y values. Therefore, we can answer in coordinate point form.

It’s B because they both equal each other I would explain more but I’m in class but the answer is definitely B
You would subtract.
The question is asking who has more, so to find out, you need to take away the smaller amount from the bigger amount. (1.25-1.05)
So Sandra bought more candy. Hope this helps!
