3 0

Step-by-step explanation:

a.

2(3x) - 5x = 4

6x - 5x = 4

x = 4

B. -5(x-4)+8x=29

-5x+20+8x=29

3x+20=29

3x=9

x=3

C. 2y=18+2(3-y)

2y=18+6-2y

2y=24-2y

4y=24

y=6

D. c = -b - 11

3c + 6 = 6b

3( -b - 11) +6 = 6b

-3b-33+6=6b

-3b-27=6b

-27=9b

3=b

(_2/3)(Raised to power 3) multiplied by (_3/2)(raised to power 2)
Irina18 [472]

Answer:

\frac{-2}{3}

Step-by-step explanation:

From the given question,

(\frac{-2}{3} )^{3} x (\frac{-3}{2} )^{2}

Applying the required principle of indices to solve the question, we have;

(\frac{-2}{3} )^{3} x (\frac{-3}{2} )^{2} = \frac{(-2)^{3} }{3^{3} } x \frac{(-3)^{2} }{2^{2} }

= \frac{-8}{27} x \frac{9}{4}

= \frac{-72}{108}

= \frac{-2}{3}

Thus, the final answer is \frac{-2}{3}.
