Se nos dice que Lucía corre 4 millas diarias. Ya que no corre los días domingo, entonces corre 6 días por semana, por lo tanto:
![4\frac{millas}{dia}\times6dias=24\text{ millas}](https://tex.z-dn.net/?f=4%5Cfrac%7Bmillas%7D%7Bdia%7D%5Ctimes6dias%3D24%5Ctext%7B%20millas%7D)
Por lo tanto, Lucía corre 24 millas por semana.
Answer:
2x^3 +7x^2+3x-2
Step-by-step explanation:
3x^3 +7x^2 -x
- ( x^3 -4x +2)
------------------------
The first step is to line up the variables by degree
3x^3 +7x^2 -x
- ( x^3 -4x +2)
----------------------------
Then distribute the minus sign
3x^3 +7x^2 -x
- x^3 +4x -2
----------------------------
2x^3 +7x^2+3x-2
The total loan payment = 300,000 * 10 Years = $3,000,000
There is a total loan cost formula solved for principal:
principal = (Total - Total * ((1 + rate)^ - # of years * 12) / (rate * # of years * 12)
The rate is the monthly loan rate = rate / 1,200 = 8 / 1,200 =
.0066666666...
principal =(3,000,000 - 3,000,000 * (1.0066666666)^-120) / (.0066666666 * 120)
<span>principal =(3,000,000 - (3,000,000 * 0.4505234643) / .8

Answer:
The number of 57-cent stamps that Julie bought is 12
Step-by-step explanation:
Given equation
0.57 s + 0.3 ( s − 6 ) = 8.64
Open bracket
0.57s + 0.3s - 1.8 = 8.64
Collect like terms
0.87s = 8.64 + 1.8
0.87s = 10.44
Divide both sides by 0.87
s = 12
The number of 57-cent stamps that Julie bought is 12
