Solve the following equation for X.
3x- 4 = 11

Answer:

The perimeter is 16 yards.

_

Step-by-step explanation:

♤You can solve using the pythagorean theorem.

♡We will be using the variable 'x' to represent the variable 'b' in the picture provided.

◇In the pythagorean theorem, a and b represents bases while the c represents the hypotenuse (diagonal).

[tex] {a}^{2} + {b}^{2} = {c}^{2} \\ {x}^{2} + {12}^{2} = {20}^{2} \\ {x}^{2} + 144 = 400 \\ \frac{ \: \: \: \: \: - 144 = - 144}{ {x}^{2} = \sqrt{256} } \\ x = 16[/tex]

Answer:

sin x= opp/hyp

sin x=18/30

sin x =3/5

cos x= adj/hyp

cos x=24/30

cos x=4/5

tan x=opp/adj

tan x=18/24

tan x=3/4

Answer:

Step-by-step explanation:

The equation of a line with a slope of "a" and containing a given point (x₀, y₀) is:

y - y₀ = a(x - x₀)

a = 11,  x₀ = -7,  y₀ = -1

So:

y - (-1) = 11(x - (-7))  

y = 11x + 77 - 1

y = 11x + 76

Jenny is 8 years old and Sammie 17 is years old.

Current age of Jennie and Sammie

Let the current age of Jennie be x.

Let the current age of Sammie be y.

Then from given data we have:

[tex]x = y-9\\4(x-5) = (y-5)[/tex]

We'll substitute value of x from equation 1 in equation 2:

[tex]4(y-9-5) = (y-5)\\3y = 51\\y=17[/tex]

Thus, from equation 1 and y = 17, we have:

[tex]x=y-9\\x=17-9\\x=8[/tex]

Thus, Jenny is 8 years old and Sammie 17 is years old.

Answer:

82 wheels

Step-by-step explanation:

7(2) + 9(4) + 8(4) = x

14 + 36 + 32 = x

82 = x

Answer:

114

Step-by-step explanation:

9 + 7 = 16

24 - 16 = 8 students on inline skates

8 x 4 wheels per skate = 32

32 x 2 shoes per person = 64

7 x 2 wheels per bike = 14

9 x 4 wheels per skate board = 36

36 + 14 + 64 = 114

Answer:

Step-by-step explanation:

So first you multiply 6 by 55. That equals 330. Then, you divide that by 44. That equals 7.5. Therefore, Pablo runs 7.5 miles in 44 minutes.

Answer:

x + (4x-6) • 2

Step-by-step explanation:

First, let's start by calling the width of the rectangle x

Because the length is 4 times the width minus 6, the equation for length will be 4x-6

The width and length together will be x + (4x-6)

You then have to times it by 2 to find the whole perimiter.

Answer:

x=6

Step-by-step explanation:

If you would like to know the value of x, you can calculate this using the following steps:

x^3 = 216

x = sqrt3(216)

x = 6

The correct result would be 6.

Answer:

Option c = [tex]\sqrt[9]{3}[/tex]

Step-by-step explanation:

One side = 18

Bottom side = 18 (equalateral triangle)

we can use phytagorues theorum:

a = the altitude (unknown)

b= one side (half of the bottom side) = 18/2 = 9

c = hypothenus = 18 (given)

a^2 + b^2 = c^2

a^2 + 9^2 = 18^2

a^2 = 18^2 - 9^2

   a^2  = 243

a = [tex]\sqrt{243}[/tex] = [tex]\sqrt{ 3 x 3 x 3 x 3 x 3 }[/tex] = [tex]\sqrt[9]{3}[/tex]

Answer:

45 boys

Step-by-step explanation:

The 3 part of the ratio refers to the number of girls.

Divide number of girls by 3 to find the value of one part of the ratio

27 ÷ 3 = 9 ← value of 1 part of the ratio, then

5 parts = 5 × 9 = 45 ← number of boys

Answer:

Their are 45 boys.

Step-by-step explanation:

Let's represent Girls by G,and Boys by B

so G = 27 and B = ? and G/B = 3:5 or 3/5

3 = 27

5. B

3B = 135

3. 3

B = 45

Answer:

P = 36 1/6 feet

Step-by-step explanation:

you can create the following proportion:

6 / 7 = 10 / x

cross-multiply:

6x = 70

x = 11 2/3

use the same ratio to write a second proportion to find the last side:

6 / 7 = 15 / x

cross-multiply:

6x = 105

x = 17 1/2

Perimeter = 7 + 11 2/3 + 17 1/2  =  28 7/6 + 7  =  29 1/6 + 7 = 36 1/6 feet
