The solution to the equation is x = 21/4

What is Linear Equation in 1 variable?

The linear equations in one variable is an equation which is expressed in the form of ax + b = 0, where a and b are two integers, and x is a variable and has only one solution

Given data ,

The equation is x + 7/2 = 5x/3

Subtracting 7/2 on both sides , we get

x = 5x/3 - 7/2

x = ( 10x - 21 ) / 6

Multiplying 6 on both sides , we get

6x = 10x - 21

Adding 21 on both sides , we get

6x + 21 = 10x

Subtracting 6x on both sides , we get

4x = 21

Divide by 4 on both sides , we get

x = 21/4

Hence , the solution for  x + 7/2 = 5x/3 is x = 21/4

Answer:

[tex]16(a + 5b)(a - 5b)[/tex]

Step-by-step explanation:

[tex]16 {a}^{2} - 400 {b}^{2} [/tex]

[tex] = > {(4a)}^{2} - {(20b)}^{2} [/tex]

[tex] = > (4a + 20b)(4a - 20b)[/tex]

Taking 4 common from each expression gives,

Answer:

x = 18

Step-by-step explanation:

Given that m is parallel to m, therefore:

(7x - 7)° = (6x + 11)° (alternate exterior angles are congruent)

Solve for x

7x - 7 = 6x + 11

7x - 6x = 7 + 11

x = 18

Answer:

The value is  [tex]CP = 0.667[/tex]

Step-by-step explanation:

From the question we are told that

    The resistance is  [tex]R = 45 \pm 0.32\ \Omega[/tex]

   The mean is  [tex]\mu = 50 \Omega[/tex]

    The standard deviation is  [tex]\sigma = 0.16 \Omega[/tex]

Generally the upper  limit  of the resistance specified in the question(i.e  upper specification limit (USL )) is

        [tex]USL = 45 + 0.32 = 45.32 \ \Omega[/tex]  

Generally the lower  limit of the resistance specified in the question(i.e  lower specification limit (USL )) is

        [tex]LSL = 45 - 0.32 = 44.68 \ \Omega[/tex]

Generally the CP of the process of manufacturing the resistor is mathematically represented as  

         [tex]C P = \frac{ USL - LSL }{ 6 * \sigma }[/tex]

=>     [tex]CP = \frac{45.32 - 44.68 }{6 * 0.16}[/tex]

=>     [tex]CP = \frac{0.64 }{0.96}[/tex]

=>     [tex]CP = 0.667[/tex]

Answer:

the value of f(5) is 26.672

Option (E) 26.672 is the correct answer

Step-by-step explanation:

Given that;

f(1) = 2 and f(x) = √( x³ + 6 )

f(5) = ?

f(5) = f(1) + ₁∫⁵ f'(x) dx

we substitute

f(5) = 2 + ₁∫⁵ √( x³ + 6 ) dx

f(5) = 2 + ₁∫⁵ √( x³ + 6 ) dx

f(5) = 2 + 24.6719

f(5) = 26.672

Therefore the value of f(5) is 26.672

Option (E) 26.672 is the correct answer

The value of f(5) is 26.672

Given the following parameters

f(1) = 2

f(x) = √( x³ + 6 )

We need to calculate the value of f(5) as shown below

f(5) = f(1) + ₁∫⁵ f'(x) dx

Substitute the given parameters

f(5) = 2 + ₁∫⁵ √( x³ + 6 ) dx

f(5) = 2 + ₁∫⁵ √( x³ + 6 ) dx

f(5) = 2 + 24.6719

f(5) = 26.672

Hence the value of f(5) from the solution is 26.672

Answer:

25, 25, 22.5, 22

Step-by-step explanation:

It gives you a hint; K = y/x. They give you what x and y are so use that to solve for the last row.

We are given all of these values:

x -> 2, 3, 4, 5

y -> 50, 75, 90, 110

Use the formula given and solve for K.

50/2 = 25

75/3 = 25

90/4 = 22.5

110/5 = 22

Answer:

A

Step-by-step explanation:

The velocity of a moving body is given by the equation:

[tex]v=t^2-5t+4 ,\, t\geq0[/tex]

Is the velocity is positive (v>0), then our object will be moving forwards.

And if the velocity is negative (v<0), then our object will be moving backwards.

We want to find between which interval(s) is the object moving backwards. Hence, the second condition. Therefore:

[tex]v<0[/tex]

By substitution:

[tex]t^2-5t+4<0[/tex]

Solve. To do so, we can first solve for t and then test values. By factoring:

[tex](t-4)(t-1)=0[/tex]

Zero Product Property:

[tex]t=1, \text{ and } t=4[/tex]

Now, by testing values for t<1, 1<t<4, and t>4, we see that:

[tex]v(0)=4>0,\, v(2)=-2<0,\,\text{ and } v(5)=4>0[/tex]

So, the (only) interval for which v is <0 is the second interval: 1<t<4.

Hence, our answer is A.

Answer: False.

Step-by-step explanation: Rational and irrational numbers are the opposites of each other. If a number is rational, it cannot possibly be irrational.

Think about it this way, can a negative number be both negative and positive? No, of course not. This is the exact same concept, albeit using rational and irrational instead of positive and negative. Still, a number can only be one or the other, never both.

Answer:

[tex]P(-2<Z<2)=95\%[/tex]

Step-by-step explanation:

From question we are told that

Sample mean [tex]\=x= 47[/tex]

Standard deviation [tex]\sigma =7[/tex]

Generally the  X -Normal is given as

      [tex]Z=\frac{x-\=x}{\sigma}[/tex]

      [tex]Z=\frac{x-47}{9}[/tex]

Analyzing the range

    [tex]P(47<x<65) = P(0< z<2.00)[/tex]

    [tex]P(47<x<65) = 95/2[/tex]

   [tex]P(47<x<65) = 47.5\%[/tex]

Mathematically

[tex]Z_1 =\frac{47-47}{9} =0[/tex]

[tex]Z_2 =\frac{65-47}{9} =2[/tex]

Empirical rule shows that

Irrational:

pi

The rational numbers are √36, 7/16, and √81 = 9 the irrational numbers are √120, √48, and π.

It is defined as the numbers in all real numbers which cannot be represented as rational numbers, in other words the irrational number cannot be expressed in the form of p/q form.

A rational number is a sort of real number that has the form p/q and does not equal zero.

From the definition of rational and irrational number, we can identify the rational and irrational numbers as below:

Rational numbers:

√36 = 6

7/16

√81 = 9

Irrational number:

√120

√48

π

Thus, the rational numbers are √36, 7/16, and √81 = 9 the irrational numbers are √120, √48, and π.
