Solve for x. -3(3x+3)= -2x+5
notsponge [240]

Answer:

x = -2

Step-by-step explanation:

So we are given the equation -3(3x + 3) = -2x + 5 and we are solving for x. We will have to try to get the equation into the form x = _. That would be our answer.

-3(3x + 3) = -2x + 5

Distribute the -3 on the left side.

-9x - 9 = -2x + 5

Add 2x to both sides to get rid of the -2x on the right side.

-9x - 9 + 2x = 5

Simplify.

-7x - 9 = 5

Add 9 to both sides to get rid of the - 9 on the left side.

-7x = 5 + 9

Simplify.

-7x = 14

Divide both sides by -7 to get rid of the coefficient of -7 on the left side.

x = 14 ÷ (-7)

Simplify.

x = -2

The answer is x = -2.

I hope you find my answer helpful. :)

An astronaut standing on a platform on the moon drops a hammer. The hammer falls 6m vertically in 2.7seconds. What is accelerati
Fantom [35]
6m Divided by 2.7 Seconds 
6/2.7=<span>2.22222222222
 2.22222222 Meters per second is end velocity
the change in velocity is Start velocity (0m/s) - end velocity (2.222222222m/s)
So the Change in velocity is 2.222222222m/s
To find acceleration it is Change in velocity (2.2222222m/s)/Time (2.7m/s)
2.222222222222/2.7=</span><span>0.82304526749
acceleration=</span><span>0.82304526749 Meters per second Squared
This also would make sense as we already know acceleration is less on the moon.
