Answer:

x=-3

Step-by-step explanation:

\frac{2}{3}\left(3x+9\right)=-2\left(2x+6\right)

Expand:

\frac{2}{3} *3x+\frac{2}{3} *9=-2*2x+(-2)(6)

2x+6=-4x-12

Subtract 6 from both sides:

2x+6-6=-4x-12-6

2x=-4x-18

Add 4x to both sides:

2x+4x=-4x-18+4x

6x=18

Divide both sides by 6:

\frac{6x}{6}=\frac{-18}{6}\\

x=-3

igor_vitrenko [27]

Answer:

30% members have voted.

Step-by-step explanation:

Given:

Number of members voted = 3

Number of members didn't vote = 7

We need to find what percentage of people voted.

Solution:

First we will find the total number of members in the election.

Now we can say that;

The total number of members in the election is equal to sum of Number of members voted and Number of members didn't vote.

framing in equation form we get;

The total number of members in the election = 7+3=10

Now we will find the percentage of people voted.

So we can say that;

Percentage of members voted can be calculated by dividing Number of members voted from The total number of members in the election and then multiplying by 100 we get;

Percentage of members voted = \frac{3}{10}\times100 = 30\%

Hence 30% members have voted.
