Answer:
Step-by-step explanation:
Since radar reports 30 tracks in one minute in which 60 seconds makes 1 minute
Let calculate using this formula
Using this formula
Percentage of time=Tracks reported in minutes/60 seconds*100
Let plug in the formula
Percentage of time=30 tracks/60 seconds*100
Percentage of time=0.5*100
Percentage of time=50%
Inconclusion The percentage of the time that radar track the aircraft is 50%
<h3>The answer is:</h3><h2>8</h2><h2 />

Answer:
<h3>
x₁ = -5, x₂ = 5</h3>
Step-by-step explanation:

It is similar to an equation
-3x-6<-5x-2
-3x+5x<-2+6
2x<4
x<4/2
x<2
* when solving inequality problems you need to switch signs when you divide a side by a negative number.
Ex.
-3x-6<-5x-2
-6+2<-5x+3x
-4<-2x
When you divide -4 by -2, switch the lesser sign to greater sign.
-4/-2>x
2>x
Which gives you the same result either way.
x<2
