9 different ways. Because there are three people and they can arrange themselves three ways three times three is nine.
<span>-5(4x+7)<25
Use distributive property(Multiply -5 by 4x and 7).
-20x - 35<25
Add 35 to both sides
-20x< 60
Divide both sides by -20 so that the only thing remaining on the left side is the variable x. *Note: When you divide a negative number on both sides of the inequality, the greater than/less than sign flips to it's opposite.
Final Answer: x> -3</span>

Answer:
The top of the escalator is 10 ft from the ground floor
Step-by-step explanation:
we know that
The function sine of angle of 39.81 degrees is equal to divide the opposite side to the angle of 39.81 degrees (distance of the top of the escalator from the ground floor) by the hypotenuse (15.5 ft)
so
Let
h ------> distance of the top of the escalator from the ground floor
sin(39.81°)=h/15.5
h=(15.5)sin(39.81°)=9.9 ft
Round to the nearest foot
h=10 ft
