Question

Solve the open sentence. 8 < 2b OR 2b + 15 < 5 A. b > –3 OR b < 4 B. b > –1 OR b < 3 C. b < –2 OR b > 3 D. b > 4 OR b < –5 D?

Answer 1

The correct answer is D. b > 4 or b < -5.

Answer 2

We are given inequalities as

First inequalities:

`8<2b`

we will solve for b

`2b>8`

divide both sides by 2

`(2b)/(2) >(8)/(2)`

`b>4`

Second inequality:

`2b+15<5`

we can solve for b

`2b+15-15<5-15`

`2b<-10`

Divide both sides by 2

`(2b)/(2) <(-10)/(2)`

`b<-5`

so, we will get

`b>4` OR
`b<-5`

so, option-D...........Answer
