The expression would be written as:
![\frac{2}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B5%7D%20)
n-3
N is any number. This expression means two-fifths of a number, subtract three. Now substitute 25 for n.
![\frac{2}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B5%7D%20)
(25)-3
=10-3
=7
Answer:
2 pounds
Step-by-step explanation:
pounds of white candy: 8.25 - (2.5 + 3.75) = 8.25 - 6.25 = 2
Answer:
![y -5 = \frac{9}{13}(x - 7)](https://tex.z-dn.net/?f=y%20-5%20%3D%20%5Cfrac%7B9%7D%7B13%7D%28x%20-%207%29)
Step-by-step explanation:
Given :
Two points are given in graph (-6, -4) and {7, 5).
The point-slope form of the equation of a straight line is:
------------(1)
Let
and ![(x_{2}, y_{2})=(-6,-4)](https://tex.z-dn.net/?f=%28x_%7B2%7D%2C%20y_%7B2%7D%29%3D%28-6%2C-4%29)
The slope of the line ![m=\frac{y_{2}- y_{1}}{x_{2}- x_{1}}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_%7B2%7D-%20y_%7B1%7D%7D%7Bx_%7B2%7D-%20x_%7B1%7D%7D)
Put all known value in above equation.
![m=\frac{-4- 5}{-6- 7}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-4-%205%7D%7B-6-%207%7D)
![m=\frac{-9}{-13}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-9%7D%7B-13%7D)
![m=\frac{9}{13}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B9%7D%7B13%7D)
The slope of the line ![m=\frac{9}{13}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B9%7D%7B13%7D)
We know m, and also know that
, so we put these value in equation 1.
![y -5 = \frac{9}{13}(x - 7)](https://tex.z-dn.net/?f=y%20-5%20%3D%20%5Cfrac%7B9%7D%7B13%7D%28x%20-%207%29)
Therefore, the equation of the line is
.
