Solve the inequality.3 - 2a < 7a. a < -2b. a < 2c. a > -2d. a > 2solve the inequality. 3m > 9a. m > 6b. m < - 6c. m < 3d. m > 3solve the inequality.|x + 6| > 15a. x > -21 or x < 9b. x < -21 or x > 9c. -21 < x < 9d. -9 < x < 9

1.) 3-2a<7

Subtract 3 from each side:

-2a<4

Divide both sides by -2, when you divide both sides of an inequality by a negative number, you also need to flip the direction of the inequality sign.

a >-2

Answer is C.

2.) 3m>9

Divide both sides by 3:

m >3

Answer is D.

3.) |x + 6| > 15

Remove the absolute value term and add a + and - to the right side:

x+6 > +/- 15

Now make 2 equations and solve x for both:

x +6<15

x >9

and

x+6 >-15

x<-21

The answer is B.

c. 16 units
