Step-by-step explanation:

1) Apply distributive property:

Subtract 10 from both sides of the equation and then divide both sides by 2:

2) Apply distributive property:

Add 3 to both sides of the equation and then divide both sides by -3:

3) Apply distributive property:

Add 4 to both sides of the equation:

Multiply both sides by :

4) Apply distributive property:

Add to both sides of the equation:

Multiply both sides by :

1) Is A- x < -3, or x> 5 (d=cant put the line under the second one)

2) C- 25<*with line under* x >with line under*30 Because its between 25, so must be more, and 30, so has to be less than 30

-10 < n < 85/4 < x ≤ 6

Step-by-step explanation:

1. Subtract 9:

-10 < n < 8

__

2. Add 12, then divide by 8:

10 < 8x ≤ 48

10/8 < x ≤ 6

5/4 < x ≤ 6 . . . . . with the fraction reduced

The rules of equality allow us the do these operations, provided that we do them to all parts of the compound inequality. That is, when we say "subtract 9", we mean ...

-1 -9 < 9 +n -9 < 17 -9

This simplifies to the inequality we show above:

-10 < n < 8

(1).Factor the expression: 15n- 18

answer

B:3(5n-6)

(2).solve for x:

-2.3(x-1.2) = -9.66

-2.3x +2.76 = -9.66

-2.3x = -9.66 - 2.76

-2.3x = -12.42

x = 5.4

answer is x = 5.4

x = -3.25

Step-by-step explanation:

- 2 - 8 = - 4x - 23

- 2 - 8 + 23 = - 4x

13 = - 4x

13 / 4 = -x

3.25 = -x

-3.25 = x
