Answer:

x=9/2

Step-by-step explanation:

4x+2=8x-16

-4x=-18

4x=18

x=18/4

x=9/2

The number is 6.

Let the unknown number be represented with y

This formula can be derived from the question: 4 (y + 2) = 8y - 16

In order to determine the value of y, take the following steps:

Combine similar terms

8 + 16 = 8y - 4y

Add similar terms

24 = 4y

Divide both sides by 4

y = 6

Answer:

Original number of sixes = 6

Original number of nines = 10

Step-by-step explanation:

We are told in the question that:

A certain number of sixes and nines is added to give a sum of 126

Let us represent originally

the number of sixes = a

the number of nines = b

Hence:

6 × a + 9 × b = 126

6a + 9b = 126.....Equation 1

If the number of sixes and nines is interchanged, the new sum is 114.

For this second part, because it is interchanged,

Let us represent

the number of sixes = b

the number of nines = a

6 × b + 9 × a = 114

6b + 9a = 114.......Equation 2

9a + 6b = 114 .......Equation 2

6a + 9b = 126.....Equation 1

9a + 6b = 114 .......Equation 2

We solve using Elimination method

Multiply Equation 1 by the coefficient of a in Equation 2

Multiply Equation 2 by the coefficient of a in Equation 1

6a + 9b = 126.....Equation 1 × 9

9a + 6b = 114 .......Equation 2 × 6

54a + 81b = 1134 ........ Equation 3

54a + 36b = 684.........Equation 4

Subtract Equation 4 from Equation 3

= 45b = 450

divide both sides by b

45b/45 = 450/45

b = 10

Therefore, since the original the number of nines = b,

Original number of nines = 10

Also, to find the original number of sixes = a

We substitute 10 for b in Equation 1

6a + 9b = 126.....Equation 1

6a + 9 × 10 = 126

6a + 90 = 126

6a = 126 - 90

6a = 36

a = 36/6

a = 6

Therefore, the original number of sixes is 6

[tex]\huge\boxed{x=9}[/tex]

Step-by-step explanation:

We know that ∠A and ∠B are the same exact length. Since one of the angles is given to us in an exact length, we can set the measures equal to each other.

[tex]4x + 9 = 45[/tex]

Let’s solve for x.

Answer:

x=6 and x=12 are parallel.

Step-by-step explanation:

If you graph x=6 it will be a straight verticle line on the x-axis where 6 is, same with x=12 (put a vertical line on 12 for the x-axis). When you put these both on the same graph you see they are directly across from each other but will never touch. Therefore, they are parallel. If you are writing this on paper, simply draw a graph to show this.

The required value for which h(x) = 18 is given as x = 7.

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Here,
The function h(x) = 2x + 4 - - - - (1)

Since h(x) =18

Substitute h(x) = 18 in equation 1,
18 = 2x + 4

Simplify
18 - 4 = 2x
x = 14 / 2
x = 7

Thus, the required value for which h(x) = 18 is given as x = 7.

Complete Question

The picture of the stem plot National  and American League is shown on the first uploaded image

Answer:

The value is [tex]\= x  = 50.14[/tex]

Step-by-step explanation:

From the question we are told that

The stem plot for National League is

            [tex]2\ \ \ \ \ 9\\3\ \ \ \ \ 1 \\4\ \ \ \ \ 2\ 6\ 7\ 8\ 8\\5 \ \ \ \ \ 3\ 5\ 5\ 5\\6 \ \ \ \ \ 3\ 3\ 7\\7[/tex]

The  sample size is  n =  14

Generally the stem plot is interpreted in this manner

   The numbers on the first column represents the tens of a two digit number while the second column holds the possible unit number the tens in the first column can be combined with

  for example 4th row

 5           3 5 5 5

is equivalent to

53 55 55 55

Generally the mean for the national league is mathematically represented as

           [tex]\= x = \frac{29 + 31 + \cdots + 67}{14}[/tex]

=>         [tex]\= x  = \frac{702}{14}[/tex]

=>         [tex]\= x  = 50.14[/tex]

Answer:

1. How many will be infected next week

From the information, there are 1000 mice in the lab.

200 mice are infected. It is expected that 90% of the mice are expected to overcome the infection and 40% uninfected mice will be infected.

If 200 mice are infected, then number of uninfected mice is:

= 1000 - 200 = 800

90% of infected mice get cured. Out of 200 mice who are infected, the number of mice getting cures is:

N(E) = P(E)×N(S)

= 0.90*200

= 180

The number of mice still infected is 200 - 180 = 20

Out of 800 uninfected mice, 40% will get infected. Number of infected mice is:

N(E) = P(E) * N(S)

= 0.40 * 800

= 320

​Total number of infected mice is 320 + 20  = 340 . Thus, the number of infected mice next week is 340

2. How many will be infected in 3 weeks

After three week, the number of infected mice is 340. Therefore, the number of uninfected mice is 1000 - 340 = 660

Now, out of 340 mice, it is expected that 90% will recover. This indicates that 10% will remain infected. Then the number of infected mice is

N(E) = P(E) * N(S)

= 0.10 * 340

=  34

​  

Out of 660 mice, 40% will be infected. The number of mice becoming infected is

N(E) = P(E) * N(S)

= 0.40 * 660

= 264

Total number of infected mice is 264 + 34 =298. Thus, the number of infected mice after two weeks is 298.

x>2

The graph would have a 2 with an open circle above it.  The line would cover all numbers greater than 2.

Step-by-step explanation:

6x-5(2x-1)<4-2x

6x-10x+5<4-2x

-4x+5<4-2x

-4x+2x<4-5

-2x<-1

x>-1÷(-2) (You flip the sign when you multiply or divide both sides by a negative number)

x>2

The idea is to use the tangent line to [tex]f(x)=\sqrt x[/tex] at [tex]x=25[/tex] in order to approximate [tex]f(25.3)=\sqrt{25.3}[/tex].

We have

[tex]f(x)=\sqrt x\implies f(25)=\sqrt{25}=5[/tex]

[tex]f'(x)=\dfrac1{2\sqrt x}\implies f'(25)=\dfrac1{10}[/tex]

so the linear approximation to [tex]f(x)[/tex] is

[tex]L(x)=f(5)+f'(5)(x-5)=5+\dfrac{x-5}{10}=\dfrac x{10}+\dfrac92[/tex]

Hence [tex]m=\frac1{10}[/tex] and [tex]b=\frac92[/tex].

Then

[tex]f(25.3)\approx L(25.3)=\dfrac{25.3}{10}+\dfrac92=\boxed{7.03}[/tex]

Answer:

[tex]f(x) = \frac{2x}{2x + 3}[/tex]

Step-by-step explanation:

Given

[tex]h(x) = \frac{2x + 3}{x}[/tex]

[tex]g(x) = \frac{2}{x}[/tex]

[tex]g(f(x)) = h(x)[/tex]

Required

Find f(x)

[tex]g(x) = \frac{2}{x}[/tex]

Substitute x for f(x)

[tex]g(f(x)) = \frac{2}{f(x)}[/tex]

Recall that

[tex]g(f(x)) = h(x)[/tex]

This gives

[tex]\frac{2}{f(x)} = \frac{2x + 3}{x}[/tex]

Cross Multiply

[tex]f(x) * (2x + 3) = 2 * x[/tex]

[tex]f(x) * (2x + 3) = 2 x[/tex]

Make f(x) the subject of formula

[tex]f(x) = \frac{2x}{2x + 3}[/tex]

Answer:

The taller mountain is Dhaulagiri, by approximately 4 meters.8163

Step-by-step explanation:

You first need to convert the height of Manaslu to cm using the table, so you multiple 26,781 feet by 30.48 cm to get 816284.88. Then you need to convert that to meters, so you divide by 100 to get 8162.8488. Lastly you round that and subtract it from 8167 to see how much taller it is.
