Please help simple
x+2/2x−2 = 1/2
Please help simple x+2/2x−2 = 1/2 - 1

Answers

Answer 1
Answer:

Answer:

no solutions

Step-by-step explanation:

x+2               1

------------- = ----------

2x-2               2

We can solve this using cross products

(x+2) *2 = 1*(2x-2)

Distribute

2x+4 = 2x-2

Subtract 2x from each side

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

4 = -2

This is never true so there are no solutions
Answer 2
Answer:

Answer:


Step-by-step explanation:

First cross multiply:

2(x+2)=2x-2

Then Simplify:

2x+4=2x-2

Finally, Solve:

2x-2x=4+2


Ans: No Solution

What is equivalent to
3/5 in fraction

Answers

Multiply both the numerator (top) and denominator (bottom) by anynumber (the same for both), and you'll have a fraction that isequivalent to the fraction you gave.

For example, multiply both by 2, and you have 6/10, which is equivalentto 3/5. Multiply both by 8, and you have 24/40, which is alsoequivalent to 3/5.

Prove that sin(Π÷14)sin(3Π÷14)sin(5Π÷14)=2​

Answers

Answer:

The correct prove will be:

sin((\pi )/(14))sin((3\pi )/(14))sin((5\pi )/(14))= (1)/(8)

Step-by-step explanation:

    sin((\pi )/(14))sin((3\pi )/(14))sin((5\pi )/(14))

            Multiply and Divide by 2cos((\pi )/(14))

= (2sin((\pi )/(14))cos((\pi )/(14))sin((3\pi )/(14))sin((5\pi )/(14)))/(2cos((\pi )/(14)))

⇒ Let (\pi )/(14) = Ф  and 7Ф = (\pi )/(2)

= sin2Ф sin3Ф sin5Ф ÷ 2cosФ

= 1/2(2sin2Фsin5Ф)sin3Ф ÷ 2cosФ

= (cos3Ф - cos7Ф) sin3Ф ÷ 4cosФ

= 1/2(2cos3Ф sin3Ф) ÷ 4cosФ               ∵cos7Ф = 0      

= sin6Ф ÷ 8cosФ

= sin(7Ф - Ф) ÷ 8cosФ                              

= (sin7ФcosФ - cos7ФsinФ) ÷ 8cosФ      ∵sin7Ф = 1  

= cosФ ÷ 8cosФ

= 1/8

Hence, The correct prove will be:

sin((\pi )/(14))sin((3\pi )/(14))sin((5\pi )/(14))= (1)/(8)

Keywords: prove, sinФ, cosФ

What is |58| in absolute value?

Answers

"So in practice "absolute value" means to remove any negative sign in front of a number, and to think of all numbers as positive (or zero)."

so your answer is { 58 } :)
The answer is 58 because there is no negative sign on the outside. For instance, -|58| this would be -58 since the negative sign is on the outside.

I need help.. 7k/8-3/4-5k/16=3/8

seven "k" over eight minus three fourths minus five "k" over sixteen equals three eighths

Answers

This is exactly like the one with the 'n's that you posted yesterday.
I guess you didn't get enough help on that one to understand it.

7k/8 - 3/4 - 5k/16 = 3/8

3/4 is the same as 6/8.
Add it to each side of the equation:

7k/8         - 5k/16 = 9/8

Multiply each side by 16 :

14k - 5k = 18

Add up the 'k's on the left side:

9k = 18

From this point, you can proceed directly to the numerical value of 'k'
if you need it.

In your question, you said you need help, and I showed you how to
strip the problem down so that the only thing left is ' k = something '.
Giving you the answer is no help.  Nobody actually needs the answer.
since 16 is their least common multiple you can get rid of all of the fractions by multiplying each fraction by 16:

16(7k/8)-16(3/4)-16(5k/16)=16(3/8)
 
14k-12-5k=6
            9k=6+12
            9k=18
              k=18/9
              k=2
