Answer:

24.8333 with 3 repeating.

Step-by-step explanation:

Lets make an equation for this.

159 - x = 15

X is what we are loooking for so lets isolate it.

Subtract 159 on both sides.

-x = -149

Since both are negative we need to simply cross it out.

x = 149

Now he bought six books, so divide 149 by 6.

You would get 24.8333 with the 3 repeating.

El ancho de un rectángulo es 15 pies menos que
Karolina [17]

Answer:

II. Longitud, L = 70 metros.

I. Ancho = 55 metros.

Step-by-step explanation:

Deje que la longitud del rectángulo sea L.

Deje que el ancho del rectángulo sea W.

Dados los siguientes datos;

Perímetro del rectángulo = 250 m

Traduciendo el problema verbal a una expresión algebraica, tenemos;

W = L - 15

Matemáticamente, el perímetro de un rectángulo viene dado por la fórmula;

P = 2 (largo + ancho)

250 = 2 (L + L - 15)

250 = 2 (2L - 15)

250 = 4L - 30

4L = 250 + 30

4L = 280

L = 280/4

Longitud, L = 70 m

Para encontrar el ancho;

W = L - 15

W = 70 - 15

Ancho = 55 m
