Answer:

x=11

Step-by-step explanation:

3x−45=−12

Add 45 to each side

3x−45+45=−12+45

3x = 33

Divide each side by 3

3x/3 = 33/3

x=11

Answer:

x=16

Step-by-step explanation:

12 is three fourths of x, there are three 1/4s that make up 12.

Divide 12 by three to find out 1/4 is.

Then simply multiply that by four.

[tex]5x+11x=16x[/tex]

To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

Distributive Property:

[tex](5x+10x)+(5x+1x)[/tex]

   /    \              /    \

   [tex](16x)[/tex]             [tex](6x)[/tex]

Therfore, by using the distributive property, [tex](5x+10x)+(5x+1x)[/tex], We get [tex]16x[/tex].

Step-by-step explanation:

y=(8-4x)/2

y=4-2x

I hope it helps

Answer:

y = 4 - 2x

Step-by-step explanation:

4x + 2y = 8

Subtract 4x on both sides,

2y = 8 - 4x

Divide 2 on both sides,

y = ( 8 - 4x ) / 2

y = 4 - 2x

pressure = F/A

= 750/ (1.7×9)

= 49 N/m²

Answer:

The radius is 7 cm

Step-by-step explanation:

We know the area of a circle is given by

A = pi r^2

49 pi = pi r^2

Divide each side by pi

49 = r^2

Take the square root of each side

sqrt(49) = sqrt(r^2)

7 = r

The radius is 7 cm

Answer:

radius = 7 cm

Step-by-step explanation:

the area (A) of a circle is calculated as

A = πr² ( r is the radius )

given A = 49π , then

πr² = 49π ( divide both sides by π )

r² = 49 ( take square root of both sides )

r = [tex]\sqrt{49}[/tex] = 7

Answer:

d

Step-by-step explanation:

Using a t-distribution calculator and finding the p-value, the correct option regarding the conclusion is given by:

a) the p-value is 0.02. We reject h0 at the 5% significance level because the p-value 0.02 is less than 0.05.

It also involves the significance level, as follows.

In this problem, a t-distribution calculator for a right-tailed  with t = 2.15 and 25 - 1 = 24 df is used to find a p-value of 0.02.

It is less than 0.05, hence option a is correct.

Answer:

 x = -3 , - 15

Step-by-step explanation:

Given:

x² + 18x + 45 = 0

Solve:

[tex]x_{1,\:2}=\frac{-18\pm \sqrt{18^2-4\cdot \:1\cdot \:45}}{2\cdot \:1}[/tex]

Simplify

[tex]-18\pm \sqrt{18^2-4\cdot \:1\cdot \:45=12[/tex]

[tex]x_{1,\:2}=\frac{-18\pm \:12}{2\cdot \:1}[/tex]

Separate the solution

[tex]x_1=\frac{-18+12}{2\cdot \:1},\:x_2=\frac{-18-12}{2\cdot \:1}[/tex]

[tex]x_1=\frac{-18+12}{2\cdot \:1}=-3[/tex]

[tex]x_2=\frac{-18-12}{2\cdot \:1}=-15[/tex]

Thus, the answer are:

Step-by-step explanation:

In this question we are given with three sides of a triangle that are as follows ,

And we are asked to :

We know that for finding perimeter of any shape we must have to add all the sides of the shape or ,

[tex] \qquad \: \underline{\boxed{\frak{Perimeter = Sum \: of \: all \: sides}}}[/tex]

Solution : -

( a )

Now adding all the three sides of triangle to find the perimeter .

[tex] \hookrightarrow \quad \: ( x + 5 ) + ( 2 x + 4 ) + ( 2x - 3 ) [/tex]

[tex] \hookrightarrow \quad \: \: x + 5 + 2x + 4 + 2x - 3[/tex]

Combining like terms :

[tex] \hookrightarrow \quad \:x + 2x + 2x + 5 + 4 - 3[/tex]

Now , solving :

[tex] \hookrightarrow \quad \: \red{\underline{ \boxed{ \frak{(5x + 6) \: cm}}}}[/tex]

( b )

Now , we are finding perimeter of triangle when value of x is 10 . So substituting value of x in given sides of triangle ,

First Side :

Second Side :

Third Side :

So , all the sides are 15 cm , 24 cm and 17 cm .

Now , adding all these to find perimeter .

[tex] \hookrightarrow \qquad \: 15 + 24 + 17[/tex]

[tex]\hookrightarrow \qquad \: 39 + 17[/tex]

[tex]\hookrightarrow \qquad \: \red{\underline{\boxed{\frak{56 \: cm}}}}[/tex]

Alternative Solution : -

As above we have find the perimeter of triangle in term of x that is ( 5x + 6 ) cm. So we can put value of x as 10 in this to get perimeter. So ,

Therefore, perimeter of triangle is 56 cm .

To find the perimeter of a shape, we should add all sides , like so :

x+5+2x+4+2x-3

Combine the x's :

x+2x+2x+5+4-3

x+4x+9-3

5x+6

5x+6 cm

The Brelynn can cut 9 pieces from the piece of ribbon that is 3/4 yard long of 1/12 yard.

Fraction number consists of two parts one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

Let's assume Brelynn can cut x pieces from the piece of ribbon that is 3/4 yard long.

So from the problem:

[tex]\rm \frac{\frac{3}{4} }{x} = \frac{1}{12}[/tex]

[tex]\rm \dfrac{3}{4} = \dfrac{x}{12}[/tex]

x = 9 pieces

Thus, the Brelynn can cut 9 pieces from the piece of ribbon that is 3/4 yard long of 1/12 yard.

Answer:

radius = 5

Step-by-step explanation:

[tex]x^2+y^2-10x+8y+16=0[/tex]

The equation of a circle is shown. What is the radius?

----------------------------------------------------------------------------------

Equation of a circle

[tex](x-a)^2+(y-b)^2=r^2[/tex]

(where (a, b) is the center and r is the radius)

Given equation:

[tex]x^2+y^2-10x+8y+16=0[/tex]

Collect like terms:

[tex]\implies x^2-10x+y^2+8y+16=0[/tex]

Subtract 16 from both sides:

[tex]\implies x^2-10x+y^2+8y=-16[/tex]

Complete the square for both variables.

Add 25 to both sides for x.  Add 16 to both sides for y.

[tex]\implies x^2-10x+25+y^2+8y+16=-16+25+16[/tex]

[tex]\implies (x^2-10x+25)+(y^2+8y+16)=25[/tex]

Factor the two variables:

[tex]\implies (x-5)^2+(y+4)^2=25[/tex]

The answer is A.thus, this is a linear model. To check,you can see visually that the points are more fitted to the line than the curve.

Linear regression is the most basic and commonly used predictive analysis. Regression estimates are used to describe data and to explain the relationship.

The difference between the linear model and the exponential model is the degree of difference of consecutive points. If their difference is constant, then it is more appropriate for the linear model. If their difference is increasing at a very fast rate, then that follows an exponential model. With that being said, let's look at the differences at every 6 month-intervals.

2700-2110 = 590

2110-1500 = 610

1500-870 = 630

870-220 = 650

Their differences are about the same having a mean of 620. Thus, this is a linear model. To check,you can see visually that the points are more fitted to the line than the curve. The answer is A.

Step-by-step explanation:

The value of y will be more as the number is repetitive, and both x and y initial three digits after the decimal are the same.

A rational number is one that has the form p/q, where p and q are integers and q is greater than zero. Some rational number examples are 1/3, 2/4, 1/5, 9/3, and so on.

The complete question is, Let x = 0.147 and let y = [tex]0.\overline{147}[/tex].  Is x a rational number? Is ya rational number? Which is larger, x or y?

Given the value of x is 0.147. As it can be written in the form of a fraction,

[tex]0.147 = \dfrac{147}{1000}[/tex], we can conclude that x is a rational number.

The value of y = [tex]0.\overline{147}[/tex] can also be written in the form of a fraction,

[tex]0.\overline{147} = \dfrac{147}{999}[/tex], therefore, we can conclude that y is also a rational number.

The value of y will be more as the number is repetitive, and both x and y initial three digits after the decimal are the same.
