Which represents the solution to the absolute value equation? 3|2x+4|-1=11

The first step for absolute value equations is to isolate the expression contained within the absolute value bars:

3|2x+4|-1 = 11
3|2x+4| = 12
|2x+4| = 4

so |2x+4| is 4 units away from 0 on a number line, but we don't know in which direction -- negative or positive? you'll have two answers.

2x+4 = 4

AND

2x+4 = -4

solve both of those two step equations and you'll get

x = 0

AND

x = -4

so 0 and -4 are your solutions.

Answer:

26π

Step-by-step explanation:

Hmm... This one is a little hard to understand because of the LaTeX.

Any way, way back to the question.  A useful piece of information:

<u>The formula for finding the circumference of a circle is 2πr or π · d :</u>

We first need to find out what x is.

Since 2 times the radius is the diameter, we can set up our equation like this:

2(x + 6) = 3x + 5

Solving gives:

2x + 12 = 3x + 5.

We subtract 2x from both sides:

+12 = x + 5

Subtract 5:

So x = 7.

Now we can plug-and-chug:

7 + 6 = 13 times 2pi (this is the radius)

21 + 5 = 26 times pi.

<u>Check:</u>

When we check 13 (radius) times 2 should equal the diameter(26)

13 * 2 = 26.

So we are correct. The answer 26π is correct.

Decrease £43 by 29% what’s the answer
borishaifa [10]

Answer:

30.53

Step-by-step explanation:

First you must find what 29% of 43 is, in order to do this we must multiply 43 by 29%

43*29% or 43*.29 is 12.47

This means that 29% of 43 is equal to 12.47

So decreasing 43 by 29% would be the same as decreasing 43 by 12.47

43-12.47=30.53

Jada is solving the equation shown below. Negative one-half (x + 4) = 6 Which is a possible first step to begin to simplify the
elena-14-01-66 [18.8K]

The two options that are the possible first step to begin to simplify the equation are (c) Multiply both sides of the equation by –2. and (d). Distribute Negative one-half over (x + 4).

<h3>How to determine which two options are the possible first step to begin to simplify the equation?</h3>

The equation is given as:

Negative one-half (x + 4) = 6

Rewrite the above equation properly

So, we have

-1/2(x + 4) = 6

A possible first step is to multiply both sides of the equation -1/2(x + 4) = 6 by -2

So, we have

x + 4 = -12

Another possible first step is to distribute the expression -1/2(x + 4) in the equation

So, we have

-1/2x - 1/2 * 4 = 6

Hence, the two options that are the possible first step to begin to simplify the equation are (c) Multiply both sides of the equation by –2. and (d). Distribute Negative one-half over (x + 4).
