Answer:
800x+400=T
Step-by-step explanation:
800 is the monthly rent and x is the variable used to represent the number of months Steve will rent the apartment, and 400 is the security deposit that is half of 800. Lastly, when putting the equation together, the left side of the equation will equal to T.
I dont get it what would make it true? more info please! sorry if im wrong.
Answer:
Both x=6 and x=22/3 are extraneous. There are no actual solutions to the given equation.
The equation given was: 2|x-7|=x-8.
Step-by-step explanation:
2|x-7|=x-8
Distribute the 2. We can do this because 2=|2|.
|2x-14|=x-8
|2x-14|=|-(2x-14)| holds since |1|=|-1|.
This means we have the following two equations to solve:
2x-14=x-8 or -(2x-14)=x-8
Let's first solve:
2x-14=x-8
Subtract x on both sides:
x-14=-8
Add 14 on both sides:
x=-8+14
Simplify:
x=6
Let's solve:
-(2x-14)=x-8
Distribute:
-2x+14=x-8
Add 2x on both sides:
14=3x-8
Add 8 on both sides:
22=3x
Divide both sides by 3:
22/3=x
So let's check both x=6 and x=22.3.
2|x-7|=x-8 for x=6:
2|6-7|=6-8
2|-1|=-2
2(1)=-2
2=-2 is not true so x=6 is extraneous.
2|x-7|=x-8 for x=22/3:
2|22/3-7|=22/3-8
2|22/3-21/3|=22/3-24/3
2|1/3|=-2/3
2/3=-2/3 is not true so x=22/3 is extraneous.
Answer:
She rounded down instead of up.
Step-by-step explanation:
When you are rounding, if the number is above 5 you round up and when the number is below 5 you round down.
