Answer:
Unit rate is 
feet per second.
Step-by-step explanation:
Unit rate is a number where one quantity is represented so that the other quantity is 1.
So we can give the unit rate of this as number of feet per 1 second.
It has traveled 692.08 ft in 21.1 seconds.
We have to find how many feet it travels in 1 second.
Unit rate = Number of feet / Number of seconds
=
= feet per second

Answer:
Step-by-step explanation:
3-(2x-5)=-4(x+2)
We simplify the equation to the form, which is simple to understand
3-(2x-5)=-4(x+2)
Remove unnecessary parentheses
3-2x+5=-4*(x+2)
Reorder the terms in parentheses
3-2x+5=+(-4x-8)
Remove unnecessary parentheses
+3-2x+5=-4x-8
We move all terms containing x to the left and all other terms to the right.
-2x+4x=-8-3-5
We simplify left and right side of the equation.
+2x=-16
We divide both sides of the equation by 2 to get x.
x=-8
<em>We can also graph inequalities on the number line. The following graph represents the inequality x≤2 . The dark line represents all the numbers that satisfy x≤2 . If we pick any number on the dark line and plug it in for x, the inequality will be true.</em>
