Using the distributive property simplify this -2(x-3)

Mathematics
1 answer:
Mnenie [13.5K]3 years ago
4 0

For this case we must simplify the following expression:

-2 (x-3)

By definition we have that the distributive property establishes that:

a (b + c) = ab + ac

So, if we have:

-2 (x-3)

We take into account the law of multiplication of signs:

- * + = -\\- * - = +

So:

-2 (x-3) = - 2x + 2 * 3 = -2x + 6

Answer:

-2x + 6

CUALES SON LOS GRADOS PARA HACER UNA GRAFICA DE PASTEL, CON LOS SIGUIENTES PORCENTAJES( 20%,50%,10%)
svlad2 [7]

Answer:

Lo primero que debemos saber, es que la gráfica de pastel nos permite dividir a una población, la cual sería el 100%, en porcentajes menores que representan algo.

En este caso tenemos los porcentajes 20%, 50%, 10%  (notar que no suman 100%, entonces nos falta algún porcentaje)

Bueno, como sabemos el gráfico (el cual es un círculo) representa el 100%.

Y en un círculo, tenemos un ángulo de 360°

Entonces comenzamos con la equivalencia:

360° = 100%

Entonces, ¿a que grado corresponde el 50%? Planteamos la ecuación:

x = 50%

Si tomamos el cociente entre las ecuaciones:

x = 50% y  360° = 100%

obtenemos:

x/360° = 50%/100%

resolviendo para x, obtenemos:

x = (50%/100%)*360° = 0.5*360° = 180°

Para los otros porcentajes hacemos lo mismo.

Para el de 20% tenemos:

y = 20%

planteamos la ecuación:

y/360° = 20%/100%

y = 0.2*360° = 72°

Finalmente, para el de 10% tendremos:

z = 10%

planteando la ecuación como antes:

z/360° = 10%/100%

z = 0.1*360 = 36°

Asi, hemos encontrado los grados correspondientes para cada porcentaje.

What number comes next? 80 POINTS!!<br> 10, 3, 5, _ <br> 8, 5, 4, _<br> 12, 6, 3, _
lyudmila [28]

Answer:

7, 3 and 0

Step-by-step explanation:

10, 3, 5, 7

Because the numbers are differ by prime numbers less than 10, i.e, the difference between the numbers are 7,5 and next will be 3.

8, 5, 4, 3.

The difference between the numbers are 3, 4 and similarly it will be differ by 5 which means next will be no. 3.

12, 6, 3, 0.

The numbers are differ by 6, 9 and next will be differ by 12 resulting the next no. 0.

5,000 tens = (5,000 x 10)

To find out how many thousands are in it,
just divide:

(5,000 x 10) / (1,000)  =  (5 x 10)  =  50 of them .
