Al sumar un número entero con el doble de su sucesor, se obtiene un total de 44. ¿De qué número se está hablando?
Vlad [161]
Basado en lo que nos dieron en la pregunta podemos decir que:
1) x sea un numero entero 
2)x+1 sea el numero sucesor del anterior
3) los dos seran sumados y el total de la suma es 44
4) el numero sucesor es multiplicado por dos antes de ser sumado con el numero entero


Entonces tenemos:
x+2(x+1)=44 \\ x+2x+2=44 \\ 3x=42 \\ x=14

En este caso el numero del cual se esta hablando es 14 para comprobar

14+2(14+1)=44 \\ 14+2(15)=44 \\ 44=44

Ann [662]

Question:

Taylor and his Dad plan to build a deck on the back of their house. First, they make a scale drawing of the deck. The scale is 1.25 inches = 2 feet.

This is the drawing: the scale drawing deck is 17 by 11

Using this drawing, enter the length, in feet, Taylor must use for the deck?Answer:

The length, Taylor must use for the deck is 27 .2 feet

Step-by-step explanation:

Given:

The dimensions  of the deck  =  17  by 11

Scale  =   1.25 inches = 2 feet.

To Find:

The length, in feet, Taylor must use for the deck

Solution:

According to the  scale

1.25 inches = 2 feet

Then

1 inch  = \frac{2}{1.25}

The length of the deck  =  17 inches

So 17  inches = 17 \times \frac{2}{1.25}

17 inches = 27.2 feet

the area of a rectangle is 99ft^2,and the L is 7ft more than twice the width. find the dimension of the rectangle.
givi [52]
A = L * W
A = 99
L = 2W + 7

99 = W(2W + 7)
99 = 2W^2 + 7W
-2W^2 - 7W + 99 = 0
(-2W + 11)(W + 9) = 0

-2W + 11 = 0
-2W = -11
W = -11/-2
W = 5.5

W + 9 = 0
W = -9 .....not this one because it is negative

so the width (W) = 5.5ft <====
L = 2W + 7 .....2(5.5) + 7 = 18 ft is the length (L) <==
