Answer: x=10

<u>Simplify both sides of the equation</u>

<u></u>4-(3x-5)=6-(2x+7)<u></u>

<u></u>4+-1(3x-5)=6+-1(2x+7) (Distribute the Negative Sign)

4+-1(3x)+(-1)(-5)=6+-1(2x)+(-1)(7)

4+-3x+5=6+-2x+-7

(-3x)+(4+5)=(-2x)+(6+-7) (Combine Like Terms)

-3x+9=-2x+-1

<u>Add 2x to both sides</u>

<u></u>-3x+9+2x=-2x-1+2x\\-x+9=-1<u></u>

<u></u>

<u>Subtract 9 from both sides</u>

<u></u>-x+9-9=-1-9\\-x=-10<u></u>

<u></u>

<u>Divide both sides by -1</u>

<u></u>-x/-1=-10/-1\\x=10<u></u>

Answer:

<h2>x = 10</h2>

Step-by-step explanation:

4-(3x-5)=6-(2x+7)\\\\/-(a+b)=-1(a+b)=(-1)(a)+(-1)(b)-\text{distributive property}/\\\\4-3x-(-5)=6-2x-7\\\\4-3x+5=6-2x-7\qquad\text{combine like terms}\\\\-3x+(4+5)=-2x+(6-7)\\\\-3x+9=-2x-1\qquad\text{subtract 9 from both sides}\\\\-3x+9-9=-2x-1-9\\\\-3x=-2x-10\qquad\text{sdd}\ 2x\ \text{to both sides}\\\\-3x+2x=-2x+2x-10\\\\-x=-10\qquad\text{change the signs}\\\\\boxed{x=10}

Answer:

Equation: 2x + 1 = 9x - 13

There are two chairs in each row.

Step-by-step explanation:

Looking at the problem, we see that Hue can form two rows of chairs with 1 left over, or 9 rows if she gets 13 more. With that information we can create the equation 2x + 1 = 9x - 13. Now let's solve for x.

2x + 1 = 9x - 13

<em>What we can do first is subtract 9x from both sides. This is done so all of the variables are on one side. Thus that becomes...</em>

2x + 1 - 9x = -13

<em>Now, combine -9x and 2x to get -7x.</em>

-7x + 1 = -13

<em>Now subtract 1 from both sides. This is done so we solve for x directly.</em>

-7x = -13 - 1

<em>Subtract -1 from -13 to get -14.</em>

-7x = -14

<em>Now divide both sides by -7.</em>

x = -14/-7

<em>Divide -14 by -7 to get 2. Remember, dividing two negatives gives you a positive!</em>

x = 2

With that, the equation is solved. There are 2 chairs in each row.

Answer:

i hope this helps

Step-by-step explanation:

2x^{2} -16=0

+16        +16

2x^{2} =16

÷2    ÷2

x^{2} = 8

\sqrt{x^{2} }= \sqrt{8}

x= \sqrt{8}

-5x^{2} +9=0

-9          -9

-5x^{2}=-9

÷-5   ÷-5

x^{2} =1.8

\sqrt{x^{2} }= \sqrt{1.8}

x= \sqrt{1.8}

6x^{2} -15=27

+15        +15

6x^{2} =42

÷6   ÷6

x^{2} =7

\sqrt{x^{2} }= \sqrt{7}

x=\sqrt{7}

There are 5 red marbles, 8 blue marbles, and 12 green marbles in a bag. What is the theoretical probability of randomly drawing
irinina [24]
The answer is 52% because there is a total of 25 marbles and if you add the red and blue marbles you get 14 which is more than the green mables which is more than half the amount of the total marbles
