Solve the equation: 84 = 7d​

Answer:

no

Step-by-step explanation:

When solving this equation you would substitute the x coordinate for x and the y coordinate for y:

[tex]17=(3*-5)+2[/tex]

Then multiply -5 and 3:

[tex]17=-15+2[/tex]

Then, add it out and you will come to the conclusion that it equals negative 13 not 17. The correct answer would be (5,17).

Answer:

They are equal

Step-by-step explanation:

4 (3 + x)

= 4 * 3 + 4 * x

= 12 + 4x

(3 + 3 + 3 + 3) + (x + x + x + x)

= 4 * 3 + 4 * x

= 12 + 4x

Therefore, 4(3+x) is equal to (3+3+3+3) + (x+x+x+x).

Hope it helps :)

Answer: 5h+4=A

Step-by-step explanation:

She gets five dollars an hour so for one hour she gets five dollars, for two hours she gets 2 times 5 dollars (10 dollars), for three hours she gets 3 times 5 dollars (15 dollars) etc...

Now replace the 1,2,3... with the variable representing the hour. In this case it would be h. So 5h=five dollars per hour. Because you only put the kid to bed once, you add four at the end

Answer:

[tex]Y=30[/tex]

Step-by-step explanation:

[tex]Y=X+13[/tex]

If X = 17, you have to add that with 13 to get Y.

[tex]17(X)+13=30\\Y=30[/tex]

That is your final answer.

Answer:

2 envases iguales de 171 litros

Step-by-step explanation:

Para calcular esto, primero necesitamos sumar los dos contenedores y cuantos litros de jugo tienen cada uno.

198 + 144 = 342 litros.

Ahora tenemos que calcular el numero minimo de envases. Si ya sabemos que es un numero par entonces lo podemos dividir en dos envases iguales sin que sobre...

342 / 2 = 171 litros

Finalmente, podemos ver que podemos dividir el jugo en 2 envases iguales de 171 litros

Answer:

102 nickels and 56 quarters

Step-by-step explanation:

Since the total amount of coins is 158, then...

q+n=158

Since the total amount of money is $19.10, and a quarter is 25 cents and a nickel is 5 cents, then...

0.25q+0.05n=19.10

Now that we have 2 equations and 2 variables, we can solve for this equation by solving the first equation for q and plugging it into the second equation.

q+n=158,

q=158-n

Plug into the other equation,

0.25(158-n)+0.05n=19.10

and solve for n

39.5-0.25n+0.05n=19.10

39.5-0.2n=19.10

-0.2n=-20.4

n=102

there are 102 nickels.

Now solve for quarters.

q+n=158

q+102=158

q=158-102

q=56

Answer:

The angles must be congruent.

Step-by-step explanation:

I.e., If a triangles angles are 100, 40 and 40, and it's sides are 5, 7 and 7, A triangle that has the angles of 100, 40 and 40, but sides of 10, 14 and 14, is similar to the first triangle.

Answer:

A

Step-by-step explanation:

We see that there are 3 in step 2 which means that the only possible answer is A

Answer:

16.26

Step-by-step explanation:

I am not completely sure what the problem is asking, but I believe that you are just supposed to take the inverse of sine. So, in your calculator, make sure it is in degrees mode, then usually you have to click the 2nd key and then sine. You use the inverse of sine when two sides are given, but you are not given the angle.

It should look like:

[tex]sin^{-1}(\frac{7}{25})[/tex], which is approximately 16.26.

Hopefully this is right, if not, please let me know. Good luck.

Answer:

None is

Step-by-step explanation:

Given

Volume and Surface area of a cube

Required

Which is linear

The volume of a cube is:

[tex]V(x) = x^3[/tex]

While the surface are is:

[tex]A(x) = 6x^2[/tex]

Where x represents the length of the side

A linear function construct is represented as:

[tex]f(x) = mx + c[/tex]

By comparing A(x) and V(x) to f(x):

f(x) do not have any form of exponent while A(x) and V(x) have.

So, we can see that both functions are not linear

Answer:

270 = number who get news from print sources

630 =  number who get news from social media

Step-by-step explanation:

Let 3x = number who get news from print sources

and 7x = number who get news from social media

Then 3x + 7x = 900

10x = 900

x = 90

3x = 3(90) = 270 = number who get news from print sources

7x = 7(90) = 630 =  number who get news from social media

Check:  270/630 = 3/7 and 270 + 630 = 900

Answer: Company B charges $(15.5+0.12x) more for x miles than company A.

Step-by-step explanation:

Let x = Number of miles.

Total charge = Flat charge + (charge per mile) x  (Number of miles)

Given:

For Company A ,

Flat charge= $45

Charge per mile =  11 cents  = 0.11   [ 1 dollar = 100 cents i.e. 1 cent = 0.01 dollar]

Total charge = 45+0.01x

For Company B,

Flat charge= $60.50

Charge per mile =  13 cents  = 0.13

Total charge = 60.50+0.13x

Difference in charge = Charge for company B -  Charge for company A

= 60.50+0.13x-(45+0.01x)

= 15.5+0.12x

Hence,  Company B charges $(15.5+0.12x) more for x miles than company A.

Answer:

The degree is 1

It is a linear function

m = -5 and b = 0

Step-by-step explanation:

Here, we want to get the degree of the equation

As we can see, it is a linear function with the highest power of as 1

That means it is of degree 1

Comparing with the general form;

y = mx + b

m = -5

b = 0
