- Set:

5x−12=−2+5(x−2)
multiply 5 by all in parentheses first
5x - 12= -2 + (5*x) + (5*-2)
5x - 12= -2 + 5x - 10
5x - 12= 5x - 12
if you subtract 5x from one side and add 12 to the other the solution is:
0= 0
This equation is one that is always true. No matter what number you put in for x, it will always be true.
Example:
5x - 12= 5x - 12
5(4) - 12= 5(4) - 12
20 - 12= 20 - 12
8= 8
Example:
5(-100) - 12= 5(-100) - 12
-500 - 12= -500 - 12
-512= -512
This will happen no matter what number x is.
ANSWER: D) All values of x make the equation true.
Hope this helps! :)
Answer:
Total Fencing Cost =$19.57
Step-by-step explanation:
If Rosalina is planning on fencing, we are talking about the Perimeter of the Flower Bed
Radius of the circular flower bed =3.5 ft
Perimeter = 
If Wire fencing Cost $0.89 per foot
Total Fencing Cost = $0.89 X 21.99=$19.57
Answer:
9 3/5
Step-by-step explanation:
When we see a percentage, we know that the base is 100. In other words, 960% is equal to 960/100
With this, its just a matter of transforming the improper fraction to a mixed number.
100 fits 9 times in 960 so there will be 9 wholes
the remaining 60/100 can be simplified to 3/5 through this process:
60/100 = 6/10 = 3/5
