All Real Numbers

Answer 1

First, solve each inequality.
So for this one: 2b + 5 < -1 first we're going to subtract 5 from both sides. Can you do it? :o)

Answer 2

yes

Answer 3

Let's see it? :o)

Answer 4

-3b+< -6

Answer 5

It should be:

2b+5<-1
-5 -5

2b<-6

What are you going to do now?

Answer 6

I'm not sure

Answer 7

Well you're trying to be b alone, so you're going to divide by 2 like this:

2b<-6
/2 /2

b<-3

Answer 8

Thanks

Answer 9

Same for the other one:
b - 4 > -4
+4 +4

b>0
