Answer:

  x = 5

Step-by-step explanation:

Perhaps you want to solve for x the rational equation ...

  (2+5x)/(3x) = (7x -18 +2x)/(3x)

Multiplying by 3x and collecting terms, we have ...

  2 +5x = 9x -18

  20 = 4x . . . . . . add 18-5x to both sides

  5 = x . . . . . . . . divide both sides by 4

The solution is x=5.

Answer:

B = 155°, C = 25°, D = 155°

Step-by-step explanation:

Assuming you require B, C, D

A and B are adjacent angles and are supplementary , that is

A + B = 180°

25° + B = 180° ( subtract 25° from both sides )

B = 155°

A and C are vertically opposite angles and are congruent, then

C = 25°

B and D are vertically opposite angles and are congruent , then

D = 155°

Answer:

$40.19

Step-by-step explanation:

50 - 0.2(50) = 50 - 10 = 40 - 0.05(40) = 40 - 2 = 38 * 1.0575 = 40.185 = $40.19

Answer:

y = -2x + 7

Step-by-step explanation:

Answer:

Step-by-step explanation:

recall   the two formulas

y = mx - b            slope-intercept

y - y1 = m(x-x1)     point-slope

with these  we can get the equation .  we also need to find the slope  m

m =  y2-y1 / x2-x1

m = 3 - (-1) / 2-4

m = 3 + 1 / -2

m = 4 / -2

m = -2

now with the slope known,  plug in either point into the point-slope formula and work to the slope-intercept formula, I'll use (2,3)  as the point to plug in.

y - 3 = -2(x-2)

y - 3 = -2x +4

y = -2x + 7

there.. that's your answer

y = -2x + 7  

Answer:

Total number of ways a hotel can purchase 5 of 12 sets and receive at least 2 defective sets = 288

Step-by-step explanation:

P.S - The exact question is -

Given - A shipment of 12 television sets contains 3 defective  sets.

To find - In how many ways can a hotel purchase  5 of these sets and receive at least 2 of the defective  sets?

Proof -

We know that The combination of n distinct objects taken k at a time is

[tex]^{n} C_{k} = \frac{n!}{k! (n-k)!}[/tex]

Now,

The number of ways hotel can receive 2 defective sets among 5 that can be purchased is

[tex]^{9} C_{3} * ^{3}C_{2} = \frac{9!}{3! (9-3)!} \frac{3!}{2! (3-2)!}[/tex]

⇒[tex]^{9} C_{3} * ^{3}C_{2}[/tex] = 84(3) = 252

Now,

The number of ways that hotel receives 3 defective sets among 5 that are purchased is

[tex]^{9} C_{2} * ^{3}C_{3} = \frac{9!}{2! (9-2)!} \frac{3!}{3! (3-3)!}[/tex]

⇒[tex]^{9} C_{2} * ^{3}C_{3}[/tex] = 36(1) = 36

Now,

Total number of ways a hotel can purchase 5 of 12 sets and receive at least 2 defective sets = 252 + 36 = 288

⇒Total number of ways a hotel can purchase 5 of 12 sets and receive at least 2 defective sets = 288

Answer:

12 for length, 6 for width

Step-by-step explanation:

Trust me its right

Answer:

12 for length 6 for width (:

Step-by-step explanation:

Answer:

Step-by-step explanation:

a solution is where both of the lines meet.  or they have the same point on each line. so you can set the equation of each line equal to the other.

for this  "solution" just look at the graph and see where the two lines meet.. and find the x coordinate of that point.

I see it meeting at x =2     get it?

Answer:

Twenty cookies deal

Step-by-step explanation:

A dozen cookies cost 18.75. A dozen is exactly 12. If you divide 18.75 by 12 you should get the unit price which is about $1.56 for each cookie. For 25.50 you just divide it by 20 and you should get about 1.20 which makes it a better deal.

Answer:

8y(7x^3-4x+2)

Step-by-step explanation:

Simplifying

4(x + 2) = 28

Reorder the terms:

4(2 + x) = 28

(2 * 4 + x * 4) = 28

(8 + 4x) = 28

Solving

8 + 4x = 28

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-8' to each side of the equation.

8 + -8 + 4x = 28 + -8

Combine like terms: 8 + -8 = 0

0 + 4x = 28 + -8

4x = 28 + -8

Combine like terms: 28 + -8 = 20

4x = 20

Divide each side by '4'.

x = 5

Simplifying

x = 5

Simplifying

2(x + 4) = 28

Reorder the terms:

2(4 + x) = 28

(4 * 2 + x * 2) = 28

(8 + 2x) = 28

Solving

8 + 2x = 28

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-8' to each side of the equation.

8 + -8 + 2x = 28 + -8

Combine like terms: 8 + -8 = 0

0 + 2x = 28 + -8

2x = 28 + -8

Combine like terms: 28 + -8 = 20

2x = 20

Divide each side by '2'.

x = 10

Simplifying

x = 10

Find the height:

Find the side of base:

Find volume:

Find the surface area:

Answer:

the height of pyramid

tan 42°=h/ DO

h=6 tan 42° = 5.4 units

the side of base a = 2DO/√2 = √2DO = 6√2 = 8.5 units

volume= V = a?h/3 = 8.52(5.4)/3 = 130.1 units

surface area{S }= a + 4×1/2×a/(a/2)² + h² =

8.5²+ 2*8.5 √((8.5/2)² + 5.4²)= 189.7 unit²

✰ [tex] \underline{ \underline{ \large{ \tt{S \: O \: L \: U \: T \: I \: O\: N}}}} : [/tex]

Basically there are two ways to find out the value of y. I'm gonna show you the both ways.

First one :

[tex] \large{ \tt{x + 25 \degree + 35 \degree = 180 \degree}} \text{(Sum \: of \: angles \: of \: a \: triangle)}[/tex]

⇾ [tex] \large{ \tt{x + 60 \degree = 180 \degree}}[/tex]

⇾ [tex] \large{ \tt{x = 180 \degree - 60 \degree}}[/tex]

⇾ [tex] \large{ \tt{x = 120 \degree}}[/tex]

[tex] \large{ \tt{x + y = 180 \degree}} \text{(Sum \: of \: angle \: in \: a \: straight \: line})[/tex]

⤑ [tex] \large{ \tt{120 \degree + y = 180 \degree}}[/tex]

⤑ [tex] \large{ \tt{y = 180 \degree - 120 \degree}}[/tex]

⤑ [tex] \boxed{ \large{ \tt{y = 60 \degree}}}[/tex]

Another way :

[tex] \large{ \tt{y = 35 \degree + 25 \degree}} [/tex] ( Exterior angle is equal to the sum of two non - adjacent interior angles )

↦ [tex] \boxed{ \large{ \tt{y = 60 \degree}}}[/tex]

➝ [tex] \large{ \boxed{ \boxed{ \tt{Our \: Final \: Answer : \underline{y = 60 \degree}}}}}[/tex]
