Answer:

5

Step-by-step explanation:

If <em>e = 7,</em> you would replace e in the expression <em>e - 2 </em>with 7 so that the expression becomes <em>7 - 2</em> which results in 5.

Does that help?

A couch and coffee table cost a total of $1080. The cost of the couch is two times the cost of the coffee table. Find the cost o
Alborosie

Answer:

$720

$360

Step-by-step explanation:

Let the cost of couch be A and that of coffee table be B

Given couch and coffee table cost $1080

That’s

A + B = $1080

Also, the cost of couch A is 2 times the cost of coffeee table B.

That’s

A = 2B

We now have two equations

A + B = 1080

A = 2B

Now ,substitute 2B for A in the first equation .

We have

A + B = 1080

2B + B = 1080

3B = 1080

Divide both sides by 3

3B/3 = 1080/3

B = 360

The coffee table cost $360

Remember A = 2B

Therefore

A = 2 x $360

A = $720

The couch cost $720 while the coffee table cost $360

una fracion reducicion a su minima expresion en igual a 1/8 . si la suma de sus terminos es 72. hallar la diferencia entre ellos
Mandarinka [93]

La diferencia entre el denominador y el númerador de la fracción es:

64 - 8 = 56.

<h3>¿Como encontrar la fracción?</h3>

Tendremos una fracción de la forma:

\frac{a}{b}

Tal que:

\frac{a}{b} = \frac{1}{8}

a + b = 72

Eso es un sistema de ecuaciones

Primero, podemos reescribir la primer ecuación como:

8a = b

Ahora podemos reemplazar "b" en la segunda ecuación por "8a", así obtenemos:

a + 8a = 72\\\\9a = 72\\\\a = 72/9 = 8

Ahora podemos obtener el valor de b:

b = 8a = 8*8 = 64

La diferencia entre a y b es:

b - a = 64 - 8 = 56
