Answer:

x = 2

Step-by-step explanation:

isolate the variable.

divide each side by factors that don't contain the variable.

therefore, x = 2

Step-by-step explanation:

2x-7=6x-15

or,2x-6x=-15+7

or,-4x=-8

or,x=8/4

or,x= 2 proved

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

Use the formal p • r • t

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:

3) no, because the slopes are different. 4) y=1/3x-7

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°

The answer to this math problem is -3, 8.

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

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.

#SPJ2

Answer:

Step-by-step explanation:

The selling price can be shown to be 13000 + 7% * 13000

Selling price = 13000(1 + 7/100) = 13000 (1 + 0.07 ) = 13000 * 1.07

Selling price = 13910

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.

Answer:

the sides of the air hockey can be used as parallel lines.

m° = angles on a straight line add up to 180. 180 - 64 = 116. 116/2 = 58°

m = 58°

the 64° given is an alternate angle to X.

X = 64°
