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

A regular hexagonal flower pot has sides that measure x−6 units. Its perimeter is 78 units.

Travka [436]

It would be: 6(x-6) = 78
6x - 36 = 78
6x = 78 + 36
x = 114/6
x = 19

In short, Your Answer would be 19

Hope this helps!

After a shopping spree at Target, John realized he spent three times more money than his brother Mike. They spent a total of $16

PSYCHO15rus [73]

Answer:

John spent around $53

Step-by-step explanation:

The equation is 3x=160

Since the "x" is already by itself on one side, divide 160 by 3

160÷3=53.333⇒

Now if that's not the way IT CAN ALSO BE:

30x3+70=160! That means John spent $90
