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:

$8$

we will solve for b

$2b>8$

divide both sides by 2

$\frac{2b}{2} >\frac{8}{2}$

$b>4$

Second inequality:

$2b+15$

we can solve for b

$2b+15-15$

$2b$

Divide both sides by 2

$\frac{2b}{2}$

$b$

so, we will get

$b>4$ OR $b$

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