The equation to describe the situation is 8p = 56
The number of packs of hot dog the neighbour bought is 7
p = number of packs of hot dogs
8 hot dogs are in each pack of hot dogs.
Altogether, they have 56 hot dogs. Therefore,
The equation to describe the situation is as follows:
The number of packs the neighbour bought can be calculated as follows:
<h3>Equation model:</h3>8p = 56
divide both sides by 8
8p / 8 = 56 / 8
p = 7

Answer:
Option C. (-x,y)
Step-by-step explanation:
we know that
A point reflected across the y-axis has the following rule
(a,b)------> (-a,b)
so
If the center of the original circle was located at (x, y)
then
the center of the new circle after the transformation will be (-x,y)
![sn = \frac{a(1 - {r}^{n}) }{1 - r}](https://tex.z-dn.net/?f=sn%20%3D%20%20%5Cfrac%7Ba%281%20-%20%20%7Br%7D%5E%7Bn%7D%29%20%7D%7B1%20-%20r%7D%20)
hence,
65=5(1-3^n)/1-3
( multiply by -2 on both sides )
130=5(1-3^n)
26=1-3^n
27=3^n
from here, you can use lg to solve for n.
lg 27 = lg 3^n
lg 27 = n lg 3
n = lg 27 ÷ lg 3
hence, n = 3
