Which choice is the correct way to 218,764 in expanded form

Answer:

n = 6

Step-by-step explanation:

Simplify [tex]\frac{1}{2}[/tex] · [tex](n-4)-7[/tex]

n/2 -2 -7 =-2n +6

n/2 - 9+ -2n +6

Move all terms containing  n  to the left side of the equation.

n/2 - 9 +2n =6

To write  2

n  as a fraction with a common denominator, multiply by

n/2 + 2n *(2/2) -9 = 6

combine 2n and (2/2)

n/2 + (2n*2)/2 -9 = 6

Combine the numerators over the common denominator.

(n+2n*2)/2 - 9 = 6

Simplify each term.

(n(1+2*2))/2 - 9 = 6

(n(1+4))/2 -9 = 6

(n*5)/ 2 - 9 = 6

5n/2 - 9 =6

Move all terms not containing  n  to the right side of the equation.

      Add  9  to both sides of the equation.

       5n/2 = 6 + 9

        5n/2 = 15

Multiply both sides of the equation by  2/5

2/5 * 5n/2 = 2/5 *15

Simplify both sides of the equation.

     2/5 * 5n/2

            Cancel the common factor of 2

            Cancel the common factor of  5

n = 2/5 *15

            Cancel the common factor of  5

 n = 2 * 3

Multiply

n = 6

Answer:

[tex]BC=26[/tex]

Step-by-step explanation:

Start with:

[tex]AB+BC=AC[/tex]

Since [tex]B[/tex] is the midpoint, we also know that:

[tex]AB=BC[/tex]

Knowing this, we can use a system of equations and substitute [tex]AB[/tex] for [tex]BC[/tex] in the equation we started with:

[tex]AB+AB=AC[/tex]

Let's identify our values:

[tex]AB=3x-1\\AC=8x-20[/tex]

Substitute:

[tex]3x-1+3x-1=8x-20[/tex]

Combine like terms:

[tex]6x-2=8x-20[/tex]

Add [tex]20[/tex] to both sides of the equation:

[tex]6x+18=8x[/tex]

Subtract [tex]6x[/tex] from both sides of the equation:

[tex]18=2x[/tex]

Divide by the coefficient of [tex]x[/tex], which is [tex]2.[/tex]

[tex]x=9[/tex]

Substitute [tex]9[/tex] into [tex]3x-1[/tex]

[tex]3(9)-1[/tex]

Solve:

[tex]AB=26[/tex]

Remember that [tex]AB=BC[/tex], thus:

[tex]BC=26[/tex]

Answer:

(6;2)

Step-by-step explanation:

AC=C-A

=(11;-3)-(2-6)

=2/3(9;3)

=(6;2)

Answer:

696

Step-by-step explanation:

[tex]\frac{m}{8} = 87[/tex]

First I would multiply each side by 8 to find what M is (because if you multiple m/8 by 8 the 8s will cancel out).

[tex]m=87*8\\m = 696[/tex]

Because any number divided by 1 would just be itself, 696/1 is just 696.

Answer: m/1= 7.125 or 7.1 (rounded)

Step-by-step explanation:

if m/8=57 then m/1 multiplied by 8 would be 57 . so you do the opposite and divide 57 by 8.

Answer: 175, 210, 245

Step-by-step explanation:

The distance covered by the Katires car after 5, 6, and 7 hours will be 175 ,210, and 245 miles.

Work is the completion of any task for example if you have done your homework in 5 hours then you have done 5 hours.

Another example of work is that if you have done your food by 1 hour it means your work duration is 1 hour so work is basically the time duration of any task which you have done.

Distance =  speed × time

Given,

Speed = 35 hours.

Distance covered in 5 hours ⇒

35 ×  5 = 175 miles.

Distance covered in 6 hours ⇒

35 ×  6 = 210 miles

Distance covered in 7 hours ⇒

35 ×  7 = 245 miles.

Hence, the distance covered by the Katires car after 5, 6, and 7 hours will be 175,210, and 245 miles.

Step-by-step explanation:

2904/4 = 726 miles per hour (against wind)

3504/4 = 876 miles per hour (with wind)

Assuming the wind stayed constant, the rate of the wind would be the difference between these two values halved

876-726=150

150/2=75 miles per hour (wind speed)

Therefore the rate in still air would be the middle value of the two:

726+75=801 miles per hour

Step-by-step explanation:

To find the common difference of the sequence subtract the previous term from the next term

That's

d = 9 - 5 = 4 or

d = 13 - 9 = 4 or

d = 17 - 13 = 4

Since it's the same for any of the terms chosen

The common difference = 4

The sequence above is an arithmetic sequence

For an nth term in an arithmetic sequence

A(n) = a + ( n - 1)d

where a is the first term

n is the number of terms

d is the common difference

From the question

a = 5

d = 4

We have

A(n) = 5 + ( n - 1)4

= 5 + 4n - 4

= 4n + 5 - 4

We have the answer as

To find the 25th term substitute the value of n that's 25 into the formula

We have

A(25) = 4(25) + 1

= 100 + 1

We have the final answer as

the denominators need to be the same so if we multiply the first fraction by 6 and the second by 5, our new equation is

24/30 - 5/30

24-5=19

19/30 is your answer

Answer & Step-by-step explanation:

[tex]\frac{4}{5}-\frac{1}{6}[/tex]

When you need to subtract fractions, the denominators (bottom) need to be the same. For this, you have to multiply both fractions until the bottom numbers are the same:

Find the lowest common multiple of the denominators:

[tex]5,10,15,20,25,30\\6,12,18,24,30[/tex]

The LCM of 5 and 6 is 30. Now you have to multiply the top and bottom of the fractions until you get a denominator of 30*:

[tex]\frac{4(6)}{5(6)}=\frac{24}{30}\\\\\frac{1(5)}{6(5)}=\frac{5}{30}[/tex]

So,

[tex]\frac{24}{30} -\frac{5}{30}[/tex]

When you subtract fractions, you only change the numerators (top). The denominator will stay the same:

[tex]\frac{24}{30} -\frac{5}{30}=\frac{19}{30}[/tex]

Since the fraction can't be further simplified,  [tex]\frac{4}{5}-\frac{1}{6}=\frac{19}{30}[/tex]

:Done

*When you are finding the same denominators, you need to multiply a single fraction's numerator and denominator by the same number. The two different fractions don't need to be multiplied by the same number:

[tex]\frac{x(a)}{y(a)}-\frac{w(b)}{z(b)}[/tex]

Subtract a on both sides:

d - a = fx

Divide f on both sides:

(d - a) / f = x

x = (d - a) / f

Where m is the slope of the line and c is the y-intercept of the line.

Zoey signed up for a streaming music service that costs $7 per month. The service allows Zoey to listen to unlimited music, but if she wants to download songs for offline listening, the service charges $0.75 per song.

Let x be the number of songs and y be the total amount. Then the equation will be

y = 0.75x + 7

The total money would Zoey have to pay in a month in which she downloaded 45 songs will be

y = 0.75 × 45 + 7

y = 33.75 + 7

y = $40.75

Answer:

Line [tex]b[/tex] is represented by the equation [tex]y = \frac{2}{5}\cdot x + 7[/tex].

Step-by-step explanation:

Let be line [tex]a[/tex] represented by [tex]2\cdot x - 5\cdot y = 15[/tex], whose explicitive form is:

[tex]5\cdot y = 2\cdot x - 15[/tex]

[tex]y = \frac{2}{5}\cdot x - 3[/tex]

As line [tex]b[/tex] is parallel to line [tex]a[/tex], its slope is equal to [tex]\frac{2}{5}[/tex]. Two lines that are parallel to each other have the same slope but different y-intercept. In addition, we know that point (-10, 3) lies on that line and we must find the y-intercept ([tex]k[/tex]):

[tex]y = \frac{2}{5}\cdot x +k[/tex]

If [tex]x = -10[/tex] and [tex]y = 3[/tex], then:

[tex]3 = \frac{2}{5}\cdot (-10)+k[/tex]

[tex]k = 3+\frac{2}{5} \cdot (10)[/tex]

[tex]k = 7[/tex]

Line [tex]b[/tex] is represented by the equation [tex]y = \frac{2}{5}\cdot x + 7[/tex].
