3/4(8x + 20) - 4x > -11
den301095 [7]

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data

3/4(8x + 20) - 4x > -11​

x ==> ?

Step 02:

Inequality :

\begin{gathered} \frac{3}{4}\cdot(8x\text{ + 20) - 4x > -11} \\ 6x\text{ + }15\text{ -4x > -11} \end{gathered}

2x + 15 > -11

2x + 15 - 15 > -11 - 15

2x > - 26

2x / 2 > -26 / 2

x > - 13

The answer is:

x > -13

Você precisa colocar suas renas, Raposa, Trovão, Cometa e Relâmpago, em uma fila única para puxar o seu trenó. No entanto, Comet
Gennadij [26K]

Answer:

If the reindeer do not fight, there are 5!=120 ways to line them up in a straight line.

Out of these, Bloopin and Rudy are together in 4!=24 times.  Similarly Rudy and Bloopin will be together 4!=24 times.  So the number of ways they are not together is 120-24-24=72 ways.

Hope this helps.    :)

Step-by-step explanation:

Spanish:

Si los renos no luchan, hay 5! = 120 formas de alinearlos en línea recta.

De estos, Bloopin y Rudy están juntos en 4! = 24 veces. De manera similar, Rudy y Bloopin estarán juntos 4! = 24 veces. Entonces, el número de formas en que no están juntas es 120-24-24 = 72 formas.

Espero que esto ayude       :)

5. the price of an ipod dropped from $299.99 to $180.55. what was the percent decrease in price? (round to nearest hundredth per
max2010maxim [7]
If you would like to know what was the percent decrease in price, you can calculate this using the following steps:

x% of $299.99 is $180.55
x% * 299.99 = 180.55
x/100 * 299.99 = 180.55
x = 180.55 * 100 / 299.99
x = 60.19%

100% - 60.19% = 39.81%

The correct result would be 39.81%.
