Answer:

X=-3

Step-by-step explanation

First of all, remove the parenthesis by distributing the value of the negative sign so it would be 4-x-1=6 , next find the like terms which is 4-1 is 3. so 3-x=6.

transpose the 3 to the other side so it would be -x=6-3

-x=3 divide both sides by -1. X=-3

Answer:

There will be 213 songs in each group.

Step-by-step explanation:

Suppose, the number of songs in each group is $x$

As he has 4 different groups of songs, so the t<u>otal number of songs in all 4 groups</u> will be: $(4*x)= 4x$

Given that, the mp3 player has a <u>total of 852 songs</u>. So, the equation will be........

$4x=852\\ \\ x=\frac{852}{4}=213$

So, there will be 213 songs in each group.

An airplane travels at 120 km/hr for 2 hours in a direction of 260° . At the end of this time, how far south.Of the airport is t

nadezda [96]

Answer:

the airplane is 130.56 km south of the airport after 2 hours

Step-by-step explanation:

given data

travel speed = 120

time travel = 2 hour

direction = 260°

solution

we get here direst distance covered by plane in 2 hours that is

distance cover = 120 × 2

distance cover = 240 kilometers

and

the south component of the distance will be here as

distance = 240 × sin(270 - 260) = - 130.56

so the airplane is 130.56 km south of the airport after 2 hours
