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.

yanalaym [24]

let the length of each shorter side be x

length of longer side= x+14

2(x+14) + 2x = 48

2x + 28 + 2x = 48

4x + 28 = 48

4x = 48-28

4x = 20

x = 5

shorter side = 5cm
