Which of the following statements demonstrates the associative property of multiplication?
1. 4 ∙ (3 ∙ 6) = (4 ∙ 3) ∙ 6
2. 6 ∙ 4 = 4 ∙ 6
3. -3 ∙ 1 = -3
4. 2(24) = 2(20 + 4)

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
