-9.63
Answer: Because the y terms cancel
Step-by-step explanation:
Hi, this approach is called the addition method.
By adding both equations we can cancel one term that contains one variable, and calculate the remaining variable.
For example, in this case:
8x + 3y = 27
+
4x-3y = 9
_______
12x = 36
Now, we can solve for x:
x = 36/12
x = 3
Now, simple replace the value of x in any equation to obtain the value of y:
4x-3y = 9
4(3)-3y =9
12-3y =9
12-9 = 3y
3 =3y
3/3 =y
y=1

![V = \frac{4}{3}\pi (8)](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7B4%7D%7B3%7D%5Cpi%20%288%29)
![V = \frac{4}{3}(8)\pi](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7B4%7D%7B3%7D%288%29%5Cpi)
![\pi =3.14](https://tex.z-dn.net/?f=%5Cpi%20%3D3.14)
![V = \frac{32}{3}(3.14)](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7B32%7D%7B3%7D%283.14%29)
![V = 33.493](https://tex.z-dn.net/?f=V%20%3D%2033.493)
V≈ 33.49
Using π on the calculator
![V = \frac{32}{3} \pi](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7B32%7D%7B3%7D%20%5Cpi)
![V = 33.510](https://tex.z-dn.net/?f=V%20%3D%2033.510)
V ≈ 33.51
Answer:
$37
Step-by-step explanation:
They have $260 and 7 days in a week which is spent and even amount everyday. Meaning we would divide 260 by 7. Therefore, your answer would be 37.14 meaning they could only spend the most of $37 a day.
