its 0 beacause there is no solution

I will give a Step by step solution to this equation

Let's solve your equation step-by-step.

−5d + 6 = 6 −5d

Step 1: Simplify both sides of the equation.

−5d + 6 = 6 −5d

−5d + 6 = 6 + −5d

−5d + 6 = −5d + 6

Step 2: Add 5d to both sides.

−5d + 6 + 5d = −5d + 6 + 5d

6 = 6

Step 3: Subtract 6 from both sides.

6 − 6 = 6 − 6

0 = 0

Answer:

0

Answer: All are methods for solving.

Answer:

YZ=16

Explanation:

XWY=20 XWZ=40, XWY is half of XWZ, which means ZWY =20. Now you can say that the triangles are congruent through the AAS postulate, so you know that YZ-16 because of CPCTC

The measure of the line segment is 16 units after applying the concept of congruence.

In terms of geometry, a triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.

It is given that:

m∠XWY = 20, m∠XWZ = 40, and XY = 16

Triangle XWY and Triangle ZWY are congruent triangles

Angle X = Angle Z = 90 degrees

Angle XWY = 20 degrees

Angle YWZ = 20 degrees

Angle Y = Angle Y (By AAA)

XY = YZ

16 = YZ

Thus, the measure of the line segment is 16 units after applying the concept of congruence.

Answer:

U= 1/2 C V2 = 1/2 (2*10(-6) F)* (5 V)2

U= 25 * 10(-6) J

Step-by-step explanation:

Answer:

C = 2W/V^2

Step-by-step explanation:

W = 1/2CV^2

W * 2 = 1/2CV^2 * 2

2W/V^2 = CV^2/V^2

2W/V^2 = C

C = 2W/V^2

Answer:

La ecuación de la trayectoria circular del avión es x² + y² = 9

Step-by-step explanation:

La forma general de la ecuación de un círculo se da como sigue;

(x - h)² + (y - k)² = r²

Dónde;

(h, k) = El centro del círculo

r = El radio del círculo

Dado que la distancia del avión a la torre es constante, tenemos la trayectoria del avión = trayectoria circular

El radio, r de la trayectoria circular = 3 km

Por lo que la trayectoria circular del avión se va a definir con respecto a la torre de control, tenemos;

El centro de la trayectoria circular del avión = La torre

Las coordenadas del centro de la trayectoria circular = (0, 0)

Por lo tanto, (h, k) = (0, 0)

Sustituyendo los valores conocidos, la ecuación de la trayectoria circular del avión se convierte en;

(x - h)² + (y - k)² = r² → (x - 0)² + (y - 0)² = r² = x² + y² = 3² = 9

La ecuación de la trayectoria circular del avión. = x² + y² = 9

Answer: A. it’s parallel

Step-by-step explanation:

just did my test.

The statement that must be true to prove m∠1 + m∠2 + m∠3 = 180

m∠1 + m∠2 = 180 - m∠3

Option B is the correct answer.

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

m∠1 + m∠2 = 180 - m∠3

m∠1 + m∠2 + m∠3 = 180

Thus,

m∠1 + m∠2 = 180 - m∠3 is m∠1 + m∠2 + m∠3 = 180.

Step-by-step explanation:

598.8

Answer:

Step-by-step explanation:

1 and 2 are corresponding angles, it's B because corresponding angles are always congruent.

In this little picture i drew up 1 and 2 are corresponding. meaning they're in the same places where the transversal crosses both parellel lines. the same goes for angles 3 and 4, 8 and 5, 7 and 6

Angles 3 and 6 are consecutive exterior angles, and those are supplementary, meaning that they add up to 180 degrees. 1 and 5 are the same way

Angles 2 and 8 are consecutive interior angles, and those are also supplementary. angles 7 and 4 are the same way.

Angles 7 and 2 and 8 and 4 you can see those are crossing on the inside, those are called alternate interior angles, and these angles are congruent to one another. meaning that 7 and 2 are congruent to one another, and 8 and 4 are also congruent, or equal to one another

Angles 3 and 5 and 1 and 6 are what as known as Alternate Exterior Angles. Those angles are on the outside part of the intersection and they are congruent if cut by a transversal. meaning that 3 and 5 are equal to one another and so is 1 and 6.

Answer:

6 boxes

Step-by-step explanation:

64 sweaters ---------> 8 boxes

48 sweaters ---------> 8 * 48/64 boxes

48 sweaters ---------> 6 boxes.

Hope it helps!!!

Answer:

6 boxes

Step-by-step explanation:

Divide the total number of sweaters by the number of boxes there are. The answer lets us know how many sweaters are in each box.

64 / 8 = 8

Now, we can divide 48 sweaters by how many sweaters are in each box. This answer lets us know how many boxes they should take.

48 / 8 = 6

Answer:

i’m pretty sure the answer is 8,234 x 10^-3

Step-by-step explanation:

Sorry if this is incorrect!

Answer:

8.234E^14

Step-by-step explanation:

A) C(7) represents the cost of an Uber for 7 miles. Since 'm' is the cost for m miles, '7' is the cost for 7 miles.

B) If Todd's total bill was $30, that means the cost (C) is 30. Replace C with 30.

30 = 1.5m+4.5

Now solve this equation.

30-4.5 = 1.5m+4.5-4.5

25.5 = 1.5m

m = 17

If Todd's total bill was $30, his Uber ride was 17 miles.

Answer:

10%

Step-by-step explanation:

Original price of flutes = $770

Discounted price = $693

To find:

Discount percentage = ?

Solution:

To find the discount percentage, we need to first find out the discount value.

Discount = Original price of flutes - Discounted price of flutes

Discount = $770 - $693 = $77

Discount percentage will be calculated on the original price.

[tex]Discount \%=\dfrac{Discount}{Original\ Price}\times 100\\\Rightarrow Discount \%=\dfrac{77}{770}\times 100\\\Rightarrow Discount \%=\bold{10\%}[/tex]

So, the discount as a percentage is 10%.

No it doesn't form a proportional relationship because yes, the ratio is constant AFTER the 5,000, you do need to hit the 5,000 first, and then it changes. So no, it's not proportional because it isn't constant throughout the entirety of the relationship. If you're just going based on the table in question, then yes it will be proportional since it doesn't have the 5,000 in it but if you're looking at it in it's entirety, no it's not.

Answer:Answer:

F = 0.84 [N]

Explanation:

In order to solve this problem we must take into account Newton's second law, which tells us that the sum of all forces applied on a body must be equal to the product of the mass of the body by its acceleration.

F = m*a

where:

F = force [N]

a = acceleration = 1.4[m/s^2]

m = mass = 0.6 [kg]

F = 0.6*1.4

F = 0.84 [N]
