Answer: x = 11.5

Step-by-step explanation: Since the line bisects angle BAC, this means angles BAD and DAC equal each other.

To find what angle DAC equals, you divide 75 by 2, which equals 37.5

Then you set 37.5 equal to (3x+3) and solve for x.

37.5 = 3x+3

34.5 = 3x

11.5 = x

Remark

Interesting question. Thanks for posting.

The small triangle has the height as the missing side.

Part One: Givens

a = 144

b = height = ?

c = 240

a^2 + b^2 = c^2

144^2 + b^2 = 240^2

20736 + b^2 = 57600                   Subtract 20736 from both sides

b^2 = 57600 - 20736

b^2 = 36864

√b^2 = √36864

b = 192

Solve for x

The relationship between the height (b) and 144 and x is

b^2 = 144 * x

36864 = 144x          Divide by 144

x = 256

Answer:

  (a) (6x -3) +(2x -6) +x = 180

  (b) m∠L = 123°

     m∠M = 36°

     m∠N = 21°

Step-by-step explanation:

a) The sum of angle measures (in degrees) is 180°. The equation reflects this fact:

  (6x -3) +(2x -6) +x = 180

__

b) The equation simplifies to ...

  9x -9 = 180

  x -1 = 20 . . . . . divide by 9

  x = 21 . . . . . . . .add 1

Then the degree measures are ...

  m∠L = (6x -3)° = (6·21 -3)° = 123°

  m∠M = (2x -6)° = (2·21 -6)° = 36°

  m∠N = x° = 21°

Answer:

6.06 km

Step-by-step explanation:

The information given in the question can be represented by the three sides if a right angled triangle.

Let the direct line from the airplane to the start of the runway be represented by x. So that applying the appropriate trigonometric function, we have;

Cos θ = [tex]\frac{adjacent}{hypotenuse}[/tex]

Cos [tex]8^{o}[/tex]  = [tex]\frac{6}{x}[/tex]

0.9903 = [tex]\frac{6}{x}[/tex]

⇒ x = [tex]\frac{6}{0.9903}[/tex]

      = 6.0588

x = 6.06 km

The direct line from the airplane to the stat of the runway is 6.06 km.

Answer: $350

Step-by-step explanation:

Terry bought the bike at $168 after using a coupon that reduced the price by 20%.

The sales price was therefore:

= 168/ (1 - 20%)

= $210

The sales price which is $210, was gotten after a 40% discount was applied on the original price.

Assume that original price was x:

x - (x * 40%) = 210

x - 0.4x = 210

0.6x = 210

x = 210/0.6

= $350

Answer:

Step-by-step explanation:

Answer:

15 + .50x ≥ 25    (20 customers)

Step-by-step explanation:

to get a minimum of $25 per week, Stacey needs to earn $10 on her paper route since she is already getting $15 per week in general. Now we can divide 10 by .50 to find out how many customers Stacey needs to make $25 per week. 10/.50 is 20 which means that Stacey needs at least 20 customers to make at least $25 per week.

(sorry if this is confusing but I hope it helped)

The equation can be used to find the number of customers is -

25 = 15 + 0.5x

The equation can be used to find the number of customers.

We have Stacey who earns $15 each week plus $ 0.50 for each customer on her paper route. She wants to earn at least $25 each week.

We have to determine which equation can she use to find x, the number of customers she needs to make exactly $25.

The equation representing the above situation is -

y = 10000 + 2000x = 2000(5 + x)

According to the question, we have -

Money earned by Stacey each week = $ 15

Additional money she earns for each customer = $0.50

Money Stacey wants to earn per week = $25

Net additional money she need = $25 - $15 = $10

Now, she earns -

$0.50 → 1 customer

$1  →  [tex]$\frac{1}{0.50}[/tex]  customers

$10 →  [tex]$\frac{1}{0.50} \times 10[/tex]  = 2 x 10 = 20 Customers.

In the form of equation, assume that she needs 'x' customers to make exactly $25.

Therefore -

25 = 15 + 0.5x

The above equation can be used to find the number of customers.

Answer:

The area would be 80

Step-by-step explanation:

Firstly we need the scale factor

At 2 to 5, the scale factor is 5/2 = 1 to 2.5

Mathematically, we have the area of a triangle as:

1/2 * b * h

So, if the other side is x ;

we have that :

1/2 * x * 2 = 8

2x = 16

x = 8

The bigger other side will be;

2.5 * 8 = 20

So the area of the second will be;

1/2 * 20 * 8 = 80

Answer:

[tex]16\ \text{miles}[/tex]

Step-by-step explanation:

In a parallelogram the diagnols bisect each other. So,

[tex]DE=EB\\\Rightarrow y+2=3y-4\\\Rightarrow 4+2=3y-y\\\Rightarrow 6=2y\\\Rightarrow y=\dfrac{6}{2}\\\Rightarrow y=3[/tex]

[tex]DE=y+2\\\Rightarrow DE=3+2\\\Rightarrow DE=5[/tex]

[tex]BD=2DE\\\Rightarrow BD=2\times 5\\\Rightarrow BD=10[/tex]

[tex]EC=2y-3\\\Rightarrow EC=2\times 3-3\\\Rightarrow EC=3[/tex]

[tex]AC=2EC\\\Rightarrow AC=2\times 3\\\Rightarrow AC=6[/tex]

The sum of the diagonals is [tex]BD+AC=10+6=16\ \text{miles}[/tex]

The sum of the lengths of the two trails is [tex]16\ \text{miles}[/tex].

Step-by-step explanation:

Just took the quiz and got it right

Answer:

a= 4

b= -1

c= 10

Step-by-step explanation:

First we start by multiplying both sides of 1/2c = 5 by 2.

c = 10

Add b to both sides of the last equation to make it a=b+5

knowing these two things, we can plug them into the first equation like this:

2(b+5) + b + 10 = 17

then you solve for b:

distribute the 2

2b + 10 + b + 10 = 17

combine like terms

3b + 20 = 17

subtract 20 from each side

3b = -3

divide by 3

b = -1

then you can plug that into the last equation again so a - (-1) =5

Subtracting a negative is the same as adding so its a + 1 = 5 or a = 4

Answer:

No

Step-by-step explanation:

Given

[tex]2x + 4y = -2[/tex]

[tex]-4x + y = -14[/tex]

Required

Is (4,-2) a possible solution?

In (4,-2)

[tex]x = 4[/tex]

[tex]y = -2[/tex]

Substitute [tex]x = 4[/tex] and [tex]y = -2[/tex] in: [tex]2x + 4y = -2[/tex]

[tex]2(4) + 4(-2) = -2[/tex]

Open all brackets

[tex]2*4 - 4*2 = -2[/tex]

[tex]8 - 8 = -2[/tex]

[tex]0 \ne -2[/tex]

The above expression shows that (4,-2) is not a solution and there is no need to check for the second equation.
