Answer:

A) [tex]27 = b + 9[/tex]

[tex]b=18[/tex]

Step-by-step explanation:

When given a balanced scale (represented by a hanger in this image), the sum of the values on one side equals the value on the other side. Thus, the equation that this hanger represents is the following:

[tex]27 = b + 9[/tex]

Use inverse operations to solve this equation,

[tex]27 = b + 9[/tex]

[tex]-9[/tex]

[tex]18 = b[/tex]

Answer:

Zero

Step-by-step explanation:

Solve the equation by subtracting 8z from both sides:

8z − 5 = 8z

-5 = 0

-5 [tex]\neq[/tex] 0

This is a false statement, because -5 is not equal to zero.

This means that there are no solutions to the equation.

So, the equation has zero solutions

Because both sides of the equation have the same variable ( they both have 8x) this equation does not have any solutions.

Answer:

  (x, y) = (4, 10)

Step-by-step explanation:

The coefficients of y are opposites, so the y-terms can be eliminated by adding the equations.

  (8x -5y) +(2x +5y) = (-18) +(58)

  10x = 40 . . . . . . simplify

  x = 4 . . . . . . . . . divide by 10

Substituting this into the second equation gives ...

  2(4) +5y = 58

  5y = 50 . . . . . . . . subtract 8

  y = 10 . . . . . . . . . .divide by 5

The solution is (x, y) = (4, 10).

Factoring is an important process that helps us understand more about our equations. Through factoring, we rewrite our polynomials in a simpler form.

It is used in asset (stock) valuation. It is used in bond trading and mortgage calculations.

Step-by-step explanation:

Given

f(x) = |x + 2|

g(x) = - (x)²

Now

(g•f) (3) = g ( 3 + 2 )

= g(5)

= - (5)²

= -25

Answer:

the probability of getting 2 greens is 2/13

Step-by-step explanation:

Answer:

you can organize them 24 different ways

The different ways can he line the textbooks up on his bookshelf is 24

The fundamental counting principle is a rule used to count the total number of possible outcomes in a situation.

Given that, Connor is organizing textbooks on his bookshelf. He has a Spanish textbook, a math textbook, a physics textbook, and a health textbook.

The number of ways to arrange n things = n!

Number of different books = 4

Number of different ways to arrange 4 different books =4!

Number of different ways to arrange 4 different books= 4 x 3 x 2 x1

Number of different ways to arrange 4 different books = 24

Hence, the different ways can he line the textbooks up on his bookshelf = 24

Answer:

58.208 times 8 equals 465.664 rounded down to 465.66

Step-by-step explanation:

Answer:

$465.66

Step-by-step explanation:

First, we are buying 8 uniforms. Therefore, the total price on a normal day would be 8x68 = $544

However, on this day, there is a 20% discount. In other words, we are only paying 80% of the original price as percentages are always out of 100.

The price after the sports discount will be 544x0.8 = $435.2

On top of this, we have to pay a sales tax of 7 percent. The 7 percent is an additional cost to the discounted price of 435.2, hence we add 0.07 (7 percent in decimals) onto 1 (100% in decimals).

This gives us 435.2 x ( 1 + 0.07 )  = 465.664.

Because currency is to 2 decimal points (1 cent), the final answer will be 465.66, or 465 dollars and 66 cents.

Answer:

34 trabajadores.

Step-by-step explanation:

Supongamos que el empresario tiene N trabajadores, y tiene la cantidad de dinero D para pagarles cada día.

Si el empresario decide pagarle 50 a cada trabajador le faltan 110.

Esto se puede reescribir como:

50*N = D + 110

(50 por número de empleados es igual que el dinero que tiene más lo que le falta para pagar)

También sabemos que si pagara 45 a cada empleado, le sobraría 60.

Esto se puede reescribir como:

45*N = D - 60

Entonces tenemos dos ecuaciones:

50*N = D + 110

45*N = D - 60

Para resolver esto, el primer paso es aislar una de las variables en una de las ecuaciones, en este caso aislaré D en la segunda ecuación.

45*N + 60 = D

Ahora podemos reemplazar esto en la primer ecuación y resolver para N

50*N = (45*N + 60) + 110

50*N = 45*N + 170

50*N - 45*N = 170

5*N = 170

N = 170/5 = 34

El empresario tiene 34 trabajadores.

Answer:

x = 20% acid = 60 ml

y = 45% acid = 40 ml

Step-by-step explanation:

Let

x = 20% acid

y = 45% acid

x + y = 100 (1)

.20x + .45y = .3 ×100

.20x + .45y = 30 (2)

From (1)

x + y = 100 (1)

x = 100 - y

Substitute x = 100 - y into (2)

.20x + .45y = 30

.20(100 - y) + .45y = 30

20 - .20y + .45y = 30

- .20y + .45y = 30 - 20

.25y = 10

y = 10/.25

y = 40 ml

Substitute y = 40 into (1)

x + y = 100

x + 40 = 100

x = 100 - 40

x = 60 ml

x = 20% acid = 60 ml

y = 45% acid = 40 ml

Answer:

(-5, 1)

Step-by-step explanation:

Eliminate the equal sides of each equation and combine.

[tex] - x - 4 = \frac{3}{5} x + 4[/tex]

Solve − x −4 =35x + 4 for x.

[tex]x = - 5[/tex]

Evaluate y when x = −5.

[tex]y = 1[/tex]

hence, the system of this equation is (-5, 1).
