What is the value of x?​

Answer:

20

Step-by-step explanation:

2 1/2 = 5/2

5/2 x 4/1 = 20/1 = 20

37.5% esa es la respuesta correcta

Answer:

37.5%

Step-by-step explanation:

Answer:

8

Step-by-step explanation:

you want to set it up like this

8/20   and   6/2x-1

then you cross multiply

so 8(2x-1)  = 16x-8

and 20*6 = 120

then you do 120= 16x-8

add 8 to both sides   (you want x by it's self so to get rid of a -8 you have to add 8)

128= 16x  

(divide both sides by 16)

128/16= 8

8=x

Step-by-step explanation:

Answer:

x = 4/3

Step-by-step explanation:

7x − 4 + 8x = 6x + 8

Answer:

x=[tex]\frac{4}{3}[/tex]

Step-by-step explanation:

So the equation is 7x-4+8x=6x+8. All we need to do is simplify. On the left side, 7x+8x=15x, so 15x-4=6x+8. Now, we bring the 6x from the right side to the left. When you bring a term from one side to another, you change its sign. As of now, the sign of 6x is positive, so we make it negative and move it to the left side. The new equation is 15x-6x-4=8. Simplifying the left side gives you a new equation of 9x-4=8. Now we move the -4 from the left side to the right side. We change the sign so it becomes 4 and we move it to the right. The equation is now 9x=8+4. 8+4=12, so the final equation is 9x=12. Now we divide by 9 on both sides, giving us the unsimplified answer of x= [tex]\frac{12}{9}[/tex]. We divide the numerator and the denominator by 3 and we get our final answer of x=[tex]\frac{4}{3}[/tex].

Answer:

Step-by-step explanation:

Add 1 and subtract 1, so that the expression won't change.

[tex]x^{4}+\frac{1}{x^{4}}-3=x^{4}+\frac{1}{x^{4}}-3 +1 - 1\\\\=x^{4}+\frac{1}{x^{4}} - 2 + 1\\\\= (x^{2})^{2} + (\frac{1}{x^{2}})^{2}- 2 *x^{2}*\frac{1}{x^{2}} - 1\\\\[/tex]

[tex]= (x^{2} -\frac{1}{x^{2}})^{2} - 1\\\\=(x^{2}-\frac{1}{x^{2}})^{2}- 1^{2}[/tex]              

(a² - b²) = (a+b)(a - b)

Here a = x² - (1/x²)  and b = 1

[tex]= [ (x^{2}-\frac{1}{x^{2}})+ 1 ] [ (x^{2} -\frac{1}{x^{2}} - 1 ][/tex]

Answer:

The median for 1 is **15**

Step-by-step explanation:

Answer:

Step-by-step explanation:

1. 7, 13, 14, 14, 16 --> 13, 14, 14 --> 14

Result/Median : 14

2. 8, 10, 13, 16, 16, 17, 20, 20 -->

10, 13, 16, 16, 17, 20 -->

13, 16, 16, 17 -->

16, 16 --> You are left with two numbers, so you find their average.

16 + 16 = 32 / 2 = 16

Result/Median: 16

Hope that helps!

Answer: the answer is 16 I think

Step-by-step explanation:

Answer: 16 inches

a^2+30^2=34^2

a^2+900=1156

      -900 -900

a^2=256

Square both sides to cancel a^2

a=16

Answer:

15a² + 21a + 19 = 0

Step-by-step explanation:

Given

(4a + 3)² = (a + 5)(a - 2)

(4a + 3)(4a + 3) = (a + 5)(a - 2 ) ← expand both sides using FOIL

16a² + 24a + 9 = a² + 3a - 10 ( subtract a² + 3a - 10 from both sides )

16a² - a² + 24a - 3a + 9 + 10 = 0 ← collect like terms

15a² + 21a + 19 = 0

Answer:

5/3

Step-by-step explanation:

Divide both sides by 0.75:

12x - 4 = 16

12x = 20

x = 20/12 = 5/3

Answer:

48 and 5%; 40 and 8%

Step-by-step explanation:

The computation of the difference between the percentage increase for each town from 2016 to 2017 is given below:

Year Ogdenville North Haverbrook

2016              960                500

2017              1008               540

So here the difference would be

For 2016 to 2017

= 1008 - 960

= 48

The percentage increase is

= 48 ÷ 960

= 5%

And,

= 540 - 500

= 40

And, the percentage increase is

= 40 ÷ 500

= 8%

Answer:

Y = 6

Step-by-step explanation:

Rearrange terms

4+ =10

+ 4 = 10

Subtract 4  from both sides of the equation:

Answer:

Step-by-step explanation:

1. 2

2. 1/4

3. 3

4. 5

5. 3/2

6. -6

7. -3

I can't see pictures, but I'm assuming you want it solved.

x+2>7.

Cancel out the 2 by subtracting 2 from both sides.

x+2>7

 -2   -2

x>5

So the inequality is x>5.
