The first reaction represented is a decomposition reaction due to the fact the bonded pair are being split apart.

The second equation is a single displacement because the B and C have switched places, which is the only change making it a single displacement. If there had been another bond and A had also moved, it would be double.

-1 + 1.9x = -6.4 + 9.2x

natka813 [3]

Answer:

0.74

Step-by-step explanation:

We can isolate x, getting 9.2x - 1.9x = -1 + 6.4

We can then simplify, getting 7.3x = 5.4, which we can solve by dividing both sides by 7.3:

x = 5.4 / 7.3 = 0.74

Answer:

5. -18x^3y^4 +54x^2y^4

6. 6x^2 -40x +50

Step-by-step explanation:

Use the distributive property. The factor outside parentheses multiplies each term inside parentheses.

__

<h3>5.</h3>

$(9xy)(-2x^2y^3+6xy)=(9xy)(-2x^2y^3)+(9xy)(6xy^3)\\\\=\boxed{-18x^3y^4+54x^2y^4}$

__

<h3>6.</h3>

$(3x-5)(2x-10)=3x(2x-10)-5(2x-10)\\\\=6x^2-30x-10x+50=\boxed{6x^2-40x+50}$
