X-(9x-10)+11=12x+3(-2x+1/3)

 x =   10 / 7

Step-by-step explanation:

X - (9x - 10)  + 11 = 12x +  3  (-2x   +   1/3)

To simplify this, we have to first open the bracket

x -  9x +10 + 11  =  12x  -   3(-2x)   +  3(1/3)

x - 9x  +  10 + 11   =  12x   - 6x  +  1

-8x  +   21   =  6x   +  1

We will now collect like term

(which implies 8x will move to the right hand side hence it becomes positive 8x and then 1 will move to the left hand side hence it becomes negative 1)

21 - 1 =  6x + 8x

20   =   14x

Now, we divide both-sides of the equation by 14

Hence;

     =      x

x =  

Dividing the numerator and the denominator by 2, x becomes;

x =  

ha!

i just did this!

18. g

20. h 30 degree turn.

21. d 90 degree angles

and also 19 is a. a sphere not a cirlcle

hope i !

pls mark me brainiest

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
