e: 1/2 x (2)=8*2    x=16
f:(-4/3)(-3/4 x)=9(-4/3)   x=-36/3= -12   x=-12
g(-8/7)(-7/8 x)=(-8/7)(-21/64)   Cross simplify and you get 3/8  x=3/8

Circle the equivalent expressions<br> 6x+18-3x-9<br> 6x-3(3x-3)<br> -3(x-3)<br> -6x+3(3+3x)-6x
melamori03 [73]

Equivalent expressions are:

6x-3(3x-3)

-3(x-3)

-6x+3(3+3x)-6x

Step-by-step explanation:

We have to simplify each expression for comparison

Expression 1:

6x+18-3x-9\\= 3x+9

Expression 2:

6x-3(3x-3)\\= 6x-9x+9\\= -3x+9

Expression 3:

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

Expression 4:

-6x+3(3+3x)-6x\\= -6x+9+9x-6x\\= -3x+9

Hence,

Equivalent expressions are:

6x-3(3x-3)

-3(x-3)

-6x+3(3+3x)-6x

Assoli18 [71]

Answer:

3 * 10^3 in scientific notation.

3,000 in standard notation.

Step-by-step explanation:

We divide:

3.9 *10^5 / 1.3 * 10^2

= ( 3.9/1.3) * (10^5 / 10^2)

= 3 * 10(5-2)

= 3 * 10^3.

This  equals 3 * 1,000 = 3000.
