What is 2(x -3) = 7 (x+24)

Mathematics

Answer:

x=34.8

Step-by-step explanation:

First thing you gotta do is distribute the parenthesis.

2(x-3)= 2x-6

7(x+24)=7x+168

2x-6=7x+168

Next, we simplify our equation and subtract 6 from both sides, along with subtracting 7x from both sides.

2x-6=7x+168

   +6         +6

2x=7x+174

-7x  -7x

-5x=174

Our final step is to divide both sides by -5.

\frac{-5x=174}{-5}

x=34.8

Answer:

x = -34.8

Step-by-step explanation:

<h2><u>solve the equation</u></h2>

2(x-3)

= 2x - 6

7(x + 24 )

= 7x + 168

put the equation together

2x - 6 = 7x + 168

now make x subject of formula:

2x - 7x = 168 +6

-5x = 174

x = 174/ -5

<h3><u>x = -34.8 </u></h3>

I dentist the slope and a point on the line
Anika [276]

Answer:

2/3 (0,-3) is one possible answer.

Step-by-step explanation:

y  -1 = 2/3(x-6)  We want to get this into the slope intercept form of a line.  We want it to be in the form y = mx + b.  Let's clear the fraction first by multiplying the whole equation through by 3.

3(y - 1) = 3[2/3(x - 6)]

3y -3 = 2(x -6)

3y - 3 = 2x -12

3y = 2x - 9  Now divide all the way through by 3 to get

y = 2/3x - 3  

y = mx + b.  The m part is the slope.  In this equation the slope is 2/3

There are in infinite amount of points on a line.  I do not know if they give you a picture or if you are just to create your own.  I am going to create a point that have x = 0.  I get to pick the point.  I could pick any number.  0 is just usually really easy.  So, if I substitute 0 for x I will get:

y = 2/3(0) - 3

y = 1  so my point is (0,-3)

Now that I think about it, I do not think that I would start out clearing the fraction even though it works.  I think that I would do it like this"

y - 1 = 2/3(x - 6)  Distribute the 2/3 through (x - 4) to get

y-1 = 2/3x -4  I can make -6 a fraction by putting it over 1.  Now we have 2/3(-6/1)  multiply across to get  -12/3.  A positive times a negative is a negative.  -12 divided by 3 is -4.

y - 1 = 2/3x -4   now add 1 to both sides.

y = 2/3x -3

Answer: First Option | 2 x 10^1

Reason: After doing 6.4 divided by 3.2, you get 2, and finally you subtract 10³ by 10². And after that subtraction, you get 10^1, Therefore the answer is the first option.

<em>I hope this helps, and Happy Holidays! :)</em>
