Okay you have to distribute the -5, giving you (-10)(-20-4+10)
-10 times -14 which is positive 140

A musician performed at three local fairs. At the first he doubled his money and spent

ziro4ka [17]

Answer:

The Musician had $29 before performing at the fairs

Step-by-step explanation:

Let the initial amount musician has be x

At the first musician doubled his money and spent

$30 , this can be written as

2(x) -30---------------------------------(1)

At the second he tripled his money and spent $54.

3(2x -30) - 54

=> 6x-90-54

=> 6x- 144--------------------------------(2)

At the third, he quadrupled his money and spent $72

4( 6x- 144) - 72

24x - 576 - 72

24x -648-------------------------------(3)

At-last he had $48

24x -648 = 48

24x = 48+ -648

24x =696

x = $\frac{696}{24}$

x = 29

Tenemos 2000 baldosascon las que nos proponrmos embaldosar dos habitaciones.Para la 1ª gastamos 3/5 de ellas,y con la 2ª,3/4de l

Setler79 [48]

Answer:

En la primera habitación son usadas 1200 baldosas.

En la segunda habitación son usadas 600 baldosas.

Sobraron 200 baldosas.

Step-by-step explanation:

Tienes 2000 baldosas, con las que se propone embaldosar dos habitaciones.

Para la primera habitación se han gastado $\frac{3}{5}$ de las baldosas. Esto se expresa como:

$\frac{3}{5}*2000$

Para multiplicar una fracción por un número entero, el número entero n se puede escribir como la fracción $\frac{n}{1}$ . Luego se multiplica los numeradores y denominadores. En este caso:

$\frac{3}{5}*2000=\frac{3}{5}*\frac{2000}{1} =\frac{3*2000}{5*1} = \frac{6000}{5}$

Para reducir la fraccion, divide 40 entre 10

$\frac{6000}{5} =$ 6000 ÷5= 1200

Entonces en la primera habitación son usadas 1200 baldosas. Por lo que las que quedan se calcula como:

2000 - 1200= 800 baldosas

De esta cantidad de baldosas que quedaron, $\frac{3}{4}$ son usadas para embaldosar la segunda habitación. Esto se expresa como:

$\frac{3}{4}*800$

Resolviendo de igual manera que en el caso de la primer habitación se obtiene:

$\frac{3}{4}*800=\frac{3}{4}*\frac{800}{1} =\frac{3*800}{4*1} =\frac{2400}{4}$ = 2400 ÷ 4= 600

Entonces en la segunda habitación son usadas 600 baldosas. Por lo que, teniendo en cuenta que se tenían 800 baldosas que quedaron de la primera habitación, las baldosas restantes se calculan como:

800 - 600= 200 baldosas

Sobraron 200 baldosas.

What is the integer of The change in a balloon's volume when it loses 450 cm3 of air.

Aleks04 [339]

Answer:

The integer change is -450 cm^3

Step-by-step explanation:

Here, we want to write the integer of the change in the volume of a ballon when it loses 450 cm^3 of air

Losing this volume means we are subtracting 450 from the original volume

This represents a change of -450 cm^3
