evaluate the expression when c=3 and d=47.
d-5c​

Answer: any number or variable adding or subtracting when moved to the other side of the equal sign changes sign. Also you can change all the signs in both sides of the equation. so -a = 6 is the same as a = -6 or -6 = a.

Answer:

x = 15, 72 degrees

Step-by-step explanation:

4x + 12 + 108 = 180

4x + 120 = 180

4x (+ 120 - 120) = 180 - 120

4x = 60

4x/4 = 60/4

x = 15

4x + 12

4(15) + 12

60 + 12

Answer:

2 21/40

Step-by-step explanation:

First, you take the fractions in the parenthesis and make the denominators alike by finding the least common multiple. Once you've done that you can add them together and then add the outer fraction. When adding the outer fraction, you need to make it into an improper fraction. I hope this helped! :)

the person could be very lazy and just dot down whatever they feel like or could take their time with the assignment an get a fairly god grade. on a four choice yes the typical score would be 70 and for a two choice test It would be around 50 depending on the amount of questions and whether the "Jimmy" gives a d4mn :)

 Mid point of a segment divides the segment in two equal parts.

Value of x is 3.

  It's given in the question,

Therefore, EF = FG = (6x + 7)

And EF + FG = EG (By segment addition postulate)

Now substitute the values in the expression

(6x + 7) + (6x + 7) = (18x - 4)

12x + 14 = 18x - 4

12x - 18x = -14 - 4

-6x = -18

x = 3

            Therefore, the value of x is 3.

Perimeter = 12 + x + 6 + 2x + 5

Perimeter = 3x + 23.

Area = ½ × b × h

Area = ½ × 12 × (x + 6)

Area = 6(x + 6)

Area = 6x + 36

Step-by-step explanation:

To add integers on the number line, you move forward, and you face right (the positive direction) when you add a positive number. As with positive numbers, to add negative integers on the number line, you move forward, but you face left (the negative direction) when you add a negative number.

Try this solution, note a) the suggested way is not the only one, b) the suggested solution is for segments AC:CB=2:1 only.

Answer:

'x+5'

Step-by-step explanation:

In the question, we are given a mathematical statement and we have to convert it into an algebraic expression using the information given above.

Let there be a number “x”.

A number 5 more than this number is the number obtained after adding 5 to the given number.

So a number 5 more than x is equal to x+5.

Hence “5 more than a number” written as an algebraic expression is “x+5”.

So, the correct answer is “x+5”.

Answer:

5+x

Step-by-step explanation:

Answer: 8.5 miles

Step-by-step explanation:

Given information

Base fee = $3.00

Fee per mile = $2.00

Distance = x

Total money spend = $20

Set equation

3 + 2x = 20

Subtract 3 on both sides

3 + 2x - 3 = 20 - 3

2x = 17

Divide 2 on both sides

2x / 2 = 17 / 2

Teniendo en cuenta la definición de sistema de ecuaciones y resolviendo por el método de sustitución, la opción correcta es la opción c: Las edades de Juan y Luis son 12 y 18 años respectivamente.

En primer lugar, debes saber que un sistema de ecuaciones es un conjunto de ecuaciones con las mismas incógnitas.

Un  sistema de ecuaciones lineales es un sistema de ecuaciones en el que cada ecuación es lineal.

Resolver un sistema de ecuaciones consiste en encontrar el valor de cada incógnita para que se cumplan todas las ecuaciones del sistema.

Es decir, en los sistemas de ecuaciones, se debe buscar los valores de las incógnitas, con los cuales al reemplazar, deben dar la solución planteada en ambas ecuaciones.

Para resolver se puede aplicar el método de sustitución.

El método mencionado consiste en despejar o aislar una de las incógnitas y sustituir su expresión en la otra ecuación. De este modo, obtienes una ecuación de primer grado con la otra incógnita.

En este caso, las incógnitas son:

Juan tiene [tex]\frac{2}{3}[/tex] años de la edad de Luis. Esto es: J= [tex]\frac{2}{3}[/tex]×L

Dentro de 6 años la edad de Juan será de [tex]\frac{3}{4}[/tex] la edad de Luis. Esto es:

(J+6)=[tex]\frac{3}{4}[/tex]×(L+6)

Entonces el sistema de ecuaciones a resolver es:

[tex]\left \{ {{J=\frac{2}{3}xL } \atop {J+6=\frac{3}{4}x(L+6) }} \right.[/tex]

Resolviendo por el método de sustitución, ya que la variable J se encuentra aislada en la primer ecuación, se decide reemplazar la expresión en la segunda ecuación, obteniendo:

[tex]\frac{2}{3} xL+6=\frac{3}{4} x(L+6)[/tex]

Resolviendo:

[tex]\frac{2}{3}[/tex]×L+ 6= [tex]\frac{3}{4}[/tex]×L+

[tex]\frac{2}{3}[/tex]×L+6= [tex]\frac{3}{4}[/tex]×L+ [tex]\frac{9}{2}[/tex]

[tex]\frac{2}{3}[/tex]×L- [tex]\frac{3}{4}[/tex]×L= [tex]\frac{9}{2}[/tex] -6

[tex]-\frac{1}{12}[/tex]×L= -[tex]\frac{3}{2}[/tex]

L=(-[tex]\frac{3}{2}[/tex]) ÷ ([tex]-\frac{1}{12}[/tex])

L= 18

Ahora sustituyendo este valor en la primer ecuación se obtiene:

J= [tex]\frac{2}{3}[/tex]×L

J= [tex]\frac{2}{3}[/tex]×18

J=12

Entonces, finalmente se obtiene que la opción correcta es la opción c: Las edades de Juan y Luis son 12 y 18 años respectivamente.
