Answer:

See explanation

Step-by-step explanation:

You are given the equation 8x+(-4)=11x+5

1. Add 8 negative x-tiles to both sides of the equation to create a zero pair on the left side. The equation then will have form

8x+(-4)+(-8x)=11x+5+(-8x)\\ \\-4=3x+5

2. Add 5 negative unit tiles to both sides of the equation to create a zero pair on the right side. The equation now is

-4+(-5)=3x+5+(-5)\\ \\-9=3x

3. Divide both sides by 3:

\dfrac{3x}{3}=\dfrac{-9}{3}\\ \\x=-3

Select the multiplication sentence that applies the associative property of multiplication to the example. Example: 6 × (4 × 2)
Sliva [168]

answer : D

A. (6 × 7) + 6 = 48

Associative property of multiplication . Here we have +6 . there is a + sign inbetween.  so it does not comes under Associative property of multiplication

B. 6 × (4 + 2) = 36

Here we have 4 +2 . there is a + sign inbetween.  so it does not comes under Associative property of multiplication

C. (6 + 4) × 2 = 20

Here we have 6 + 4 . there is a + sign inbetween.  so it does not comes under Associative property of multiplication

D. (6 × 4) × 2 = 48

Here we have 6 times 4 times 2.  so it comes under Associative property of multiplication
