Answer:
-4 < x ≤ -3
Step-by-step explanation:
The compound inequality needs to be separated into its two parts in order to obtain a solution.
__
We can do a little preliminary work to make the solutions easier.
2x +6 ≤ x +3 < 3x +11 . . . . . given
x +3 ≤ 0 < 2x +8 . . . . . . . . subtract x+3
<h3>left side</h3>x +3 ≤ 0
x ≤ -3 . . . . . . . subtract 3
<h3>right side</h3>0 < 2x +8
0 < x +4 . . . . divide by 2
-4 < x . . . . . . subtract 4
<h3>solution</h3>Now, we can rearrange these back into a compound inequality.
-4 < x ≤ -3
_____

Answer:
Step-by-step explanation:
In 2002, a robot explored a tunnel 210 feet long inside the
Great Pyramid in Egypt. The robot could travel about 10 feet per
minute.
The speed of the robot is 10 feet per minute
we need to find the equation for giving distance y
the robot travel in x minutes
to time is x minutes
Distance = speed x time
speed=10, distance is y and time is x
