Hey there!!

Given equation :

... 3x - 2 + 5x = 4x + 5 - 2x

Combining like terms :

... 8x - 2 = 2x - 5

Subtracting 2x on both sides :

... 6x - 2 = - 5

Adding 2 on both sides :

... 6x = - 3

Dividing by 6 on both sides :

... x = -1/2 = -0.5

Hence, the answer is -0.5

Hope my answer helps!

P=-3w+9 <br><br><br><br>tell me the steps I already have the steps
anastassius [24]
You're solving for w for I assume.

P= -3w+9, put -3w on the left side and P on the right side.
3w= -P+9, divide both sides by 3.
w= -P+9 over 3.
w= -P over 3 plus  9 over 3.
(Final Answer):
w= -p over 3 plus 3.

Hope this helps.

in a population distribution a score of x=28 corresponds to z=-1.00 and a score of x=34 what is the mean and standard deviation
irakobra [83]
x=28\implies z=\dfrac{28-\mu}\sigma\implies \mu-\sigma=28

x=34\implies z=\dfrac{34-\mu}\sigma\implies \mu+\sigma z=34

We need the exact value of z to find a proper solution, but a general one can still be found. Subtracting the first equation from the second gives

(\mu+\sigma z)-(\mu-\sigma)=34-28\implies (z+1)\sigma=6\implies \sigma=\dfrac6{z+1}

Plug this into either equation and you get

\mu-\dfrac6{z+1}=28\implies \mu=28+\dfrac6{z+1}

(It's guaranteed that z\neq-1 in this case because that already corresponds to x=28.)
