Two more than4 times a number is -18

jonny [76]

-5, work backwards. you know 2 + 4 * ? = -18.
start by subtracting 2 from both sides giving you 4 * ? = -20.
now you divide 4 from both sides giving you ? = -5

i used ? to represent the missing number btw!!

34.7% of city employees ride the bus to work. Last year, 5.2% of city employees rode the bus to work. What is the relative chang

DaniilM [7]

Answer:

$5.67\%$

Step-by-step explanation:

The relative change is defined by the following equation:

$Relative\hspace{3}change=\frac{x-x_r_e_f_e_r_e_n_c_e}{x_r_e_f_e_r_e_n_c_e}$ (1)

Where:

$x=Value\hspace{3}of\hspace{3}indicator\hspace{3}in\hspace{3}period\hspace{3}2$

$x_r_e_f_e_r_e_n_c_e=Value\hspace{3}of\hspace{3}indicator\hspace{3}in\hspace{3}period\hspace{3}1$

With this in mind, let's replace the values in the equation (1):

$Relative\hspace{3}change=\frac{34.7-5.2}{5.2}=\frac{29.5}{5.2}=5.673076923\approx5.67\%$

Un boligrafo cuesta 30 ptas mas que un lapiz. Un muchacho ha comprado 8 boligrafos y 15 lapices. En total le han costado 700 pta

Firdavs [7]

Por un sistema de ecuaciones, tiene-se que:

Cada lapiz cuesta 20 ptas.
Cada boligrafo cuesta 50 ptas.

-------------------------

Considera-se un sistema de ecuaciones, con cada boligrafo custando x y cada lapiz custando y.

Boligrafo cuesta 30 mas que un lapiz, o sea, $x = 30 + y$
8 boligrafos y 15 lapices cuesta 700, o sea, $8x + 15y = 700$

-------------------------

Aplicando el primer ecuación en la segunda, tiene-se el cuesto de cada lapiz:

$8x + 15y = 700$

$8(30 + y) + 15y = 700$

$240 + 8y + 15y = 700$

$23y = 460$

$y = \frac{460}{23}$

$y = 20$

Cada lapiz cuesta 20 ptas.

-------------------------

Por fin, el cuesto de cada boligrafo es dado por:

$x = 30 + y = 30 + 20 = 50$

Cada boligrafo cuesta 50 ptas.
