Hi there!
Let's solve this equation step by step!
![|x| - 7 = 6](https://tex.z-dn.net/?f=%20%7Cx%7C%20%20-%207%20%3D%206)
First add 7 to both sides.
![|x| = 13](https://tex.z-dn.net/?f=%20%7Cx%7C%20%20%3D%2013)
Next we need to take a look at the meaning of the stripes between our variable. Those stripes mean we are dealing with an absolute value function. The absolute value stripes make everything between the stripes positive; also when we plug in a number. In this particular question we can plug in both -13 and 13 at the position of n, because when -13 is made positive, it fulfils the equation.
Hence,
![x= 13](https://tex.z-dn.net/?f=x%3D%2013)
or
![x = - 13](https://tex.z-dn.net/?f=x%20%3D%20-%2013)
~ Hope this helps you!
Answer:
Each person runs 3 miles in a relay race.
Step-by-step explanation:
Given:
Distance of Relay race m = 12 miles.
The expression m divided by 4 is the distance each person runs in a relay race that is m miles.
Each person runs in relay race = ![\frac{m}{4}](https://tex.z-dn.net/?f=%5Cfrac%7Bm%7D%7B4%7D)
Now given the total distance of the relay race is 12 miles.
i.e. value of m = 12 miles
Now substituting the value of m in above equation we get;
Each person runs in relay race = ![\frac{m}{4} = \frac{12}{4}=3 \ miles](https://tex.z-dn.net/?f=%5Cfrac%7Bm%7D%7B4%7D%20%3D%20%5Cfrac%7B12%7D%7B4%7D%3D3%20%5C%20miles)
Hence each person runs 3 miles in a relay race.
If 3 pounds cost $8.31, then the product is being sold as 1 for $2.77.
If 5 pounds cost $12.59, then the product is being sold as 1 for $2.51.
It is better to buy 5 pounds for $12.59 because you are getting more for your money.
Answer:
ll
Step-by-step explanation:
ll
(x+8)(x-6)= 0
x^2-48+8x-6x=0
x^2-48+2x=0
x+8=0 x-6=0
x= -8 x=6
The answer is -8 and 6, I did the process in case you need it
