Giving this if someone can help me with this problem. After Becca's half-marathon, her pedometer showed 23,580 steps, while Alex recorded 2.42 x 10⁴ steps after the same race. What is the combined amount of the steps?

Answer:

[tex]g=\frac{2m+b}{k}[/tex] ⇒ 2nd answer

[tex]x=\frac{c}{(a+b)}[/tex] ⇒ 1st answer

Step-by-step explanation:

To solve any equation for one of its variable do that:

∵ [tex]\frac{2m+b}{g}=k[/tex]

→ Multiply both sides by g to take g to the right side

∴ [tex]\frac{(2m+b)(g)}{g}=k(g)[/tex]

∴ 2m + b = kg

→ Divide both sides by k, to move k to the left side

∵ [tex]\frac{2m+b}{k}=\frac{kg}{k}[/tex]

∴ [tex]\frac{2m+b}{k}=g[/tex]

→ Switch the two sides

∴ [tex]g=\frac{2m+b}{k}[/tex]

∵ ax + bx = c

→ Take x as a common factor from the both terms on the left side

∴ x(a + b) = c

→ Divide both sides by (a + b) to move it to the right sides

∴ [tex]\frac{x(a+b)}{(a+b)}=\frac{c}{(a+b)}[/tex]

∴ [tex]x=\frac{c}{(a+b)}[/tex]

Answer: 6x+1250

Step-by-step explanation:

Amount already in the register = $1250

Number of phones sold every hour = 6

Price of the phone = x

The expression that represents the total amount of money that he should have in the register in a given hour will be:

= $1250 + $6x.

Therefore, option C that is 6x + 1250 is the correct answer.

Answer:

The sorted steps are;

1) Write the equations: 10·x + 8·y = 472 and 9·x + 8·y = 456

2) Multiply to get one variable to eliminate: -90·x - 72·y = -4248 and 90·x + 80·y = 4560

3) Eliminate x's: 8·y = 312

4) Solve for y: y = 39 (39 buses)

5)Plug back in to find x: 10·x + 8·(39) = 472

6) Solve for x: x = 16 (16 vans)

Step-by-step explanation:

Let x = The number of students in each van and y = The number of students in each bus

We have;

For High School A;

10·x + 8·y = 472...(1)

For High School B;

9·x + 8·y = 456...(2)

Multiply equation (1) by (-9) and equation (2) by 10 to get

(10·x + 8·y) × (-9) = 472 × (-9)

-90·x -72·y = -4,248...(3)

9·x + 8·y × (10)= 456 × (10)

90·x + 80·y = 4,560...(4)

Add equation (3) to (4) gives;

-90·x -72·y + 90·x + 80·y = -4,248 + 4,560

90·x - 90·x -72·y + 80·y = -4,248 + 4,560

8·y = 312

y = 312/8 = 39

y = 39

Substituting the value of y in equation (1), gives;

10·x + 8·y = 10·x + 8 × 39 = 472

10·x + 312 = 472

10·x  = 472 - 312 = 160

10·x  = 160

x = 160/10 = 16

x = 16

The number of students in each van = x = 16 students

The number of students in each bus = y = 39 students.

Answer:

= 1 7/12

Step-by-step explanation:

6 1/2 - 4 11/12 =

6 6/12 - 4 11/12 =

5 18/12 - 4 11/12 =

=1 7/12

To check if the answer is right or wrong, you can add 1 7/12 to 4 11/12

4 11/12 + 1 7/12 = 5 18/12 = 6 6/12 = 6 1/2

Answer:

Y=16x+86

Step-by-step explanation:

Step-by-step explanation:

given data:

gained = $1,570

amount invested = $29,000

0.11x – 0.07( $29,000 – x ) = 1540

0.11x – ( 2030 – 0.07x ) = 1540

0.11x + 0.07 = 1540 +2030

0.18x = 3570

divide both sides by 0.18

x = 19833.33 ( amount invested at 11%.

$29,000 – 19833.33

= $9166.7 ( amount invested at 7%)

Answer:

1). Mean = 2.275

2). Median = 2 vehicles

Step-by-step explanation:

From the given table,

Number of vehicles (x)         Frequency (f)      (f)×(x)             Cumulative freq.

                  0                                    11                  0                           11

                  1                                     52                52                        63

                  2                                    66                132                      129

                  3                                    35                105                      164

                  4                                    19                  76                       183

                  5                                    12                  60                       195

                  6                                     5                  30                       200

                                                                          [tex]\sum (f\times x) = 455[/tex]

Number of households = 200

Mean = [tex]\sum \frac{f.x}{n}[/tex]

          = [tex]\frac{455}{200}[/tex]

         = 2.275

Median = value of [tex]\frac{(n+1)}{2}th[/tex] observation

             = value of [tex]\frac{201}{2}th[/tex] observation

             = Value of 100.5th observation

             = Since 100.5th observation lies in the row of cumulative freq. = 129

             = 2

Therefore, median number of registered vehicles per California household

= 2 vehicles

Answer:

E)3

Step-by-step explanation:

4/3-1=2

3+1/2=2

First, You cross multiply.

(x - 1)(x + 1) = 8

x^2 - 1 = 8

Now subtract 8 from both sides.

x^2 - 9 = 0

x^2 - 9 is a difference between 2 squares.

(x + 3)(x - 3) = 0

For an equation with only multiplying to be equal to 0, one of its factors must be 0.

So either x + 3 = 0 or x - 3 = 0.

So x could be -3 or 3.

The answer is (E).

Complete Question

The  diagram for this question is shown on the first uploaded image

Answer:

The position of the emitter is  [tex]E =  +  72.9 \  cm\ from\ the\ center [/tex]

The position of the stone is   [tex]S =  - 72.9 \  cm\ from\ the\ center [/tex]

Step-by-step explanation:

From the question we are told that

   The  length is  l =  178 cm

    The  width is  w  =  102 cm  

Generally the position of the stone along the horizontal axis is mathematically evaluated as

         [tex]h  =  \frac{178}{2}[/tex]

=>      [tex]h  = 89 \  cm   [/tex]

Generally the position of the emitter along the vertical axis is mathematically evaluated as

         [tex]k =  \frac{102}{2}[/tex]

=>      [tex]k  = 51 \  cm   [/tex]      

Generally the  resultant position of both stone and the emitter is

       [tex]R  =  \pm \sqrt{h^ 2  - k^2}[/tex]

=>     [tex]R  = \pm  \sqrt{89^ 2  - 51^2}[/tex]

=>     [tex]R  = \pm 72.9 \  cm   [/tex]

Hence the position of the emitter is  [tex]E =  +  72.9 \  cm[/tex]

            the position of the stone is   [tex]S =  - 72.9 \  cm[/tex]

Step-by-step explanation:

Step-by-step explanation:

[tex]3(4x - 3) = - 4 + 7[/tex]

Expand :

[tex]3(4x - 3) = 12x - 9 \\ 12x - 9 = - 4 + 7[/tex]

Simplify : Add values

[tex]12x - 9 = 3[/tex]

Collect like terms and simplify

[tex]12x = 3 + 9 \\ 12x = 12[/tex]

Divide both sides of the equation by 12

[tex] \frac{12x}{12} = \frac{12}{12} [/tex]

Simplify

[tex]x = 1[/tex]

Answer:

x = 1

Step-by-step explanation:

Original Equation:

3(4x - 3) = -4 + 7

Use the distributive property.

3 x 4x = 12x

3 x -3 = -9

Equation:

12x - 9 = -4 + 7

Add 4 to both sides.

12x - 5 = 7

Add 5 to both sides.

12x = 12

Divide both sides by 12

x = 1

Answer:

The total amount she paid would be $105.50.

Answer:

25.5 is the tip -- 110.50 is the total bill.

Step-by-step explanation:

You would calculate .30 (move the decimal over twice to switch from a percentage to a decimale) multiplied with 85 and this gives you 25.5.

85 * .3 = 25.5

Depending on the rest of the question, I added the tip to the amount of the dinner cost to obtain the total bill. You will need to see what the rest of the question is in order to verify which answer you are looking for.

Answer:

The point at (4,5) on the graph of f(x) translates for f(x-2)+7​ is (6,12)

Step-by-step explanation:

Function of graph : f(x)

Rule : f(x)→f(x-c)

When the graph shifts to right by c units

Coordinates (x,y)→(x+c,y)

Rule : f(x)→f(x)+c

When the graph shifts up by c units

Coordinates (x,y)→(x,y+c)

So, Graph f(x-2)+7

Now given graph f(x)

Shift this right by 2 units and then shift up by 7 units

So, f(x)→ f(x-2)+7

Now , Translation of point(4,5)

Using rule :

When shift by 2 units right

(4,5) →(4+2,5)=(6,5)

Now  shift up by 7 units

(6,5) →(6,5+7)=(6,12)

So, the point at (4,5) on the graph of f(x) translates for f(x-2)+7​ is (6,12)
