Answer:
No, Victoria doesn't have enough. She doesn't have enough because 15% off of 139.99 is 118.99. But then their is a 7% sales tax. So once you add the sales tax you get $127.32 and her max is $125.

Answer:
![Width = W = 2x-5](https://tex.z-dn.net/?f=Width%20%3D%20W%20%3D%202x-5)
Step-by-step explanation:
Given Data:
Length of rectangle = L =
------->(Equation 1)
Area of rectangle = A =
square inches ------->(Equation 2)
To find out:
Width of rectangle = W = ?
Formula:
Area = A = L×W
![Width = W = \frac{A}{L}](https://tex.z-dn.net/?f=Width%20%3D%20W%20%3D%20%5Cfrac%7BA%7D%7BL%7D)
Solution:
![Width = W = \frac{A}{L}](https://tex.z-dn.net/?f=Width%20%3D%20W%20%3D%20%5Cfrac%7BA%7D%7BL%7D)
![Width = W = \frac{8x^{2} - 2x - 45 }{4x+9}](https://tex.z-dn.net/?f=Width%20%3D%20W%20%3D%20%5Cfrac%7B8x%5E%7B2%7D%20-%202x%20-%2045%20%7D%7B4x%2B9%7D)

Answer:
x = y/2 - 1/2
Step-by-step explanation:
you can use the slope-intercept form of a line first, then change to terms of 'x'
y = mx + b where 'm' is the slope and 'b' is the y-intercept
if we use two points on the line, such as (-1, -1) (0, 1), we can find the slope
m = 1-(-1) / 0-(-1)
m = 2/1
b = 1
Slope-Intercept form: y = 2x + 1
in terms of 'x':
2x = y - 1
x = y/2 - 1/2
Answer:
let the two numbers be x and y
x+y=45(equation 1)
x-y=5(equation 2)
from equation (1) y=45-x(equation 3)
substitute 45-x for y in equation 2
x-(45-x)=5
x-45+x=5
x+x-45=5
2x-45=5
2x=45+5
2x=50
x=50/2
x=25
