Answer:

2m^7n^4/3

Step-by-step explanation:

Step-by-step explanation:

Given

5x + 2x + 2 = 9x + 4

9x - 5x - 2x = 2 - 4

9x - 7x = - 2

2x = - 2

x = - 2 / 2

Therefore x = -1.

therefore lhs is equal to rhs

Answer:

C and D are parallel

Step-by-step explanation:

If b⊥c and b⊥d, then that means that they are both parallel because they both have a 90 degree anglewith line B.

Answer:

| | (Parallel)

Step-by-step explanation:

I'm assuming that is what it is asking. if b and c are perpendicular, that means they form 90 degrees on all angles. The same for b and d. So if both c and d are perpendicular to b, then they are parallel.

Answer:

The image of the point (2, 3) after the reflection across the y-axis will be: (-2, 3)

Step-by-step explanation:

We know that when a point, let say P(x, y), is reflected across the y-axis, the sign of x-coordinate is reversed but y-coordinate remains the same.

In other words, the rule is:

P(x, y) → P'(-x, y)

Here, P'(x, y) is the image of the original point P(x, y) after the reflection across the y-axis.

Considering the point

Let us reflect the point A(2, 3) across the y-axis.

We know the rule:

P(x, y) → P'(-x, y)

so

A(2, 3) → A'(-2, 3)

Thus, the image of the point (2, 3) after the reflection across the y-axis will be: (-2, 3)

Answer:

  AB = 7

  AC = 21

Step-by-step explanation:

Because AD is an angle bisector it divides the triangle into proportional parts. That is ...

  AC/DC = AB/BD

  (28 -AB)/9 = AB/3 . . . . use AC = 28 -AB

  28 -AB = 3AB . . . . . . . . multiply by 9

  28 = 4AB . . . . . . . . add AB

  AB = 28/4 = 7 . . . . divide by 4

  AC = 28 -7 = 21

The lengths AB and AC are 7 and 21, respectively.

_____

Additional comment

The triangle ABC cannot exist. The reason is that its side measures are 7, 12, and 21. The sum of 7 and 12 is not greater than 21, so the side measures do not satisfy the triangle inequality.

For the triangle to exist, the sum of AB and AC cannot exceed 24 for the given values of BD and DC.

Answer:

The final price including tax is $41.89

Step-by-step explanation:

The following items are on sale:

Sleeved dress $17.99

Skirt $16.19

T-shirt $8.99

Subtotal $43.17

The cheapest item is the T-shirt for $8.99 and it will be discounted by 30%:

$8.99 - 30/100 * $8.99 = $8.99 - $2.70 = $6.29

The total sale price is now: $43.17-$2.70=$40.47

Now we add the 3.5% tax:

$40.47 + 3.5/100 * $40.47 = $40.47 + $1.42 = $41.89

The final price including tax is $41.89

Answer:

x=1337/528

Step-by-step explanation:

-314x-214x=-1312-25

-528x=-1337

x=1337/528

Answer:

Step-by-step explanation:

add 314x to both sides

-314+25=214x-1312

+314x     +314x

add 1312 to both sides

25=528x-1312

+1312       +1312

1337=528x

x=1337/528

i dont thing you can simplify to a whole number...hopefully this helps a little :)

Answer:

Three times a variable added to a different variable divided by six is equal to two times the different variable minus the first variable.

Step-by-step explanation:

Answer:

No Solution

Step-by-step explanation:

2x + y = 1

y = 1 - 2x

4x + 2(1 - 2x) = -2

4x +2 - 4x = -2

2 = -2

The statement is false, therefore there is no solution.

Given:

The mean number of emails adele received during a week was 51.

The numbers received for the six days were 39, 57, 70, 45, 71, 32.

To find:

The number of emails received on the seventh day.

Solution:

Let x be the number of emails received on the seventh day.

We know that,

[tex]\text{Mean}=\dfrac{\text{Sum of observations}}{\text{Number of observations}}[/tex]

[tex]51=\dfrac{314+x}{7}[/tex]

Multiply both sides by 7.

[tex]357=314+x[/tex]

Subtract 314 from both sides.

[tex]357-314=x[/tex]

[tex]43=x[/tex]

Therefore, she received 43 emails on the seventh day.

The student took 5400 seconds to finish her assessment.

Given,

A student takes 1.5 hours to complete her midterm.

We have to find how many seconds it took to finish her midterm assessment.

One hour = 60 minutes

1 minute = 60 seconds

We have,

A student takes 1.5 hours to complete her midterm.

1.5 hours = to complete the assessment.

Converting 1.5 hours into seconds.

1 minutes = 60 seconds

Multiplying 60 on both sides.

60  x 1 minutes = 60 x 60 seconds

60 minutes = 3600 seconds

1 hour = 60 minutes

1 hour = 3600 seconds

Multiplying 1.5 on both sides.

1.5 x 1 hour = 1.5 x 3600 seconds

1.5 hours = 5400 seconds.

Thus the student took 5400 seconds to finish her assessment.
