Hello :D

Let's form an equation:

x/5 = 27

Let's form another equation:

(x+y)/7 = 34

Rearrange equation one so it is x = 27 x 5 = 135

Now we can substitute this value into equation 2:

(135 + y)/7 = 34

135 + y = 238

y = 238 - 135

y = 103

Answer is 103

Answer:

103 christmas trees.

Step-by-step explanation:

total trees sold in the first five days:

[tex]27 \times 5 = 135[/tex]

total trees sold in this week:

[tex]34 \times 7 = 238[/tex]

The answer is:

[tex]238 - 135 = 103[/tex]

Answer:

B). 55

Answer:

-3/8

Step-by-step explanation:

8y = 4 - 3x

~Divide 8 to everything

y = 1/2 - 3/8x

~Reorder

y = -3/8x + 1/2

In slope intercept form [ y = mx + b ] m resembles the slope so -3/8 is the slope.

Answer:

y = -5/4 - 31/5

Step-by-step explanation:

A: (-1,-7) and B: (9,1)

Slope: (-7-1)/(-1-9) = -8/-10 = 4/5

Slope: 4/5. Point (9,1)

y-1 = 4/5 (x-9)

y-1 = 4/5x - 36/5

y = 4/5x - 36/5 + 1

y = 4/5x - 31/5

Perpendicular bisector = Y = - 5/4x - 31/5

Answer:

7x + 3

Step-by-step explanation:

old - new =

(4x**2 + 7x + 3) - (4x**2) = 7x + 3

Based on the information given, the other number will be 112 - x

Value of the first number = x

Value of the second number = y

Sum of the numbers = 112

Therefore, the value of the second number will be:

x + y = 112

y = 112 - x

In conclusion, the value of the second number is 112 - x.

Step-by-step explanation:

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

−19=b−6

Step 1: Flip the equation.

b−6=−19

Step 2: Add 6 to both sides.

b−6+6=−19+6

b=−13

Answer:

a) Kiara ha adquirido una línea de telefonía móvil con internet a un Coste Fijo de 10 soles y un Tasa de Consumo de 1,5 soles por hora consumida.

b) El Coste total por 48 horas de consumo de la línea telefónica con internet es 82 soles.

a) Nota - Puesto que la ecuación que describe el Coste ya existe en el enunciado, entonces se entiende el verbo "Expresa" como "Describa en sus propias palabras".

Como puede apreciarse el Coste de la línea telefónica móvil aumenta linealmente con el Tiempo de consumo por parte del usuario. En consecuencia, la función de Coste queda definida como sigue:

[tex]C(t) = C_{o} + r\cdot t[/tex] (1)

Donde:

Entonces, tenemos que Kiara ha adquirido una línea de telefonía móvil con internet a un Coste Fijo de 10 soles y un Tasa de Consumo de 1,5 soles por hora consumida.

b) Una característica de las Funciones Lineales es que tanto su Dominio como Rango comprenden al Conjunto de todos los Números Reales, al ser de Pendiente constante esta Función.

Por tanto, el Dominio y el Rango de la Función en cuestión es el Conjunto de todos los Números Reales.

c) Si sabemos que [tex]C_{o} = 10[/tex], [tex]r = 1,5[/tex] y [tex]t = 48[/tex], entonces el Coste Total por concepto de 48 horas de consumo es:

[tex]C(48) = 10 + 1,5\cdot (48)[/tex]

[tex]C(48) = 82[/tex]

El Coste total por 48 horas de consumo de la línea telefónica con internet es 82 soles.

Answer:

x+n

Step-by-step explanation:

The expression for another number will be 25 - x.

An expression is a combination of some mathematical symbol such that arithmetic operator and variable such that all are constrained and create an equation.

In other meaning, expression is very useful to determine the end or root value of constraint.

For example 3x +5y

The constraint of expression is represented as = or <, >.

Let's say another number is y

Then,

Sum of both number

x + y = 25

y = 25 - x

Hence "The expression for another number will be 25 - x".

The line AB is not a perpendicular bisector of CD.

Perpendicular bisectors are lines that divides another line into two equal parts.

From the diagram, we can see that line CD cuts AB at the centre. Hence we can say that CD is a perpendicular bisector of AB.

The same is not applicable to line AB passing through CD. The line AB did not bisect (divide equally) line CD.

Hence we can conclude that line AB is not a perpendicular bisector of CD.

Answer:

Below in bold.

Step-by-step explanation:

A = (-2)^3 = -8.

B = (3)^3 = 27.

j^(3*3) = j^9 and j^(1*3) = j^3

j^9 / j^3 = j^6

So x = 6.

y = 3.

m^(3 * 3) = m^9.
