Question

Solve -np-40>10 for n.

Answer 1

It's solved like a regular equation for the most part.

First add 40 to both sides.
Next divide both sides by p. At thins point you should have -n>50/p
This is where it is slightly different from a regular equation.
You then divide both sides by negative 1 to make n positive, but when you divide an inequality by a negative you flip the sign from > to < or vice versa.
So you should now have n<-50/p

Sure~

Answer 4

Create a compound inequality to represent the air pressure range.

Can the air pressure in this town be 24 inches? Justify your answer by solving the inequalities in Part A.

The average air pressure in another town is 29 inches, but the actual pressure is within 4 inches of the average. Write and solve an inequality to find the range of air pressure in this town.
