Step-by-step explanation:
|2x - 1| - |-2| > |1 - 4|
|2x - 1| - 2 > 3
|2x - 1| > 5
Either 2x - 1 > 5 or 2x - 1 < -5.
Hence, x > 3 or x < -2.
If you had an equation such as 50%x=20, I would convert the percent to a decimal first. So, 0.50x=20. Then I would change the decimal into a simplified fraction. In this case it is 1/2. So, 1/2x=20. Then I would reciprocate the fraction and multiply that by 20. So x=20*2/1. From this, we would get x=40/1, but the 1 is not necessary, so we can write the final answer as x=40.
Answer:
6 inches
Step-by-step explanation:
Formula for surface area of a cylinder:
Plug in values and solve for the radius:
Divide both sides by 
Subtract 90 from both sides
Use the quadratic equation to find the roots
±
(sorry for formatting, Brainly doesn't
allow equations with ± in them)
and 
and 
and 
and 
and 
and 
We can't have a negative radius, so that leaves us with r=6 in.
Well a markup is the amount added to the current price so 75% added to 27$ then subtract 40%
