Answer:

x > 4

Step-by-step explanation:

x+3>19-3x
x+3x +3 > 19
4x > 19 -3
4x > 16
x > 16/4
x > 4

Solution set:

x= (4, + ∞), x∈R

Solution set as set builder notation:

A= {x | x>4, x∈R}

Find the lowest common denominator of the following fractions.5/n-2 and n+2/ n^2-4 n - 2 n2 - 4 (n - 2)(n2 - 4)

DanielleElmas [232]

Answer:

(n-2)(n+2)

Step-by-step explanation:

The denominator of the second fraction is the difference of squares, so can be factored using the formula for that.

(n^2 -4) = (n -2)(n +2)

Now, you will note that the second fraction has a numerator that is equal to one of the factors in the denominator. In other words, the whole fraction can be simplified to ...

(n +2)/((n +2)(n -2)) = 1/(n -2) . . . . with the restriction n≠-2

This reduced form of the fraction has the same denominator as the first fraction, so you can say that the lowest common denominator is that: (n -2).

If there is some reason you don't want to reduce the second fraction, the lowest common denominator will be (n -2)(n +2).

The high school soccer team can have no more than 26 players. Write and solve an inequality to determine how many more players c

Mariana [72]

Answer:

The inequality to determine how many more players can make the team is:

$x+17\leq 26$

On solving it we get : $x\leq 9$

Thus, the number of players that can still make in the team must be no more than 9.

Step-by-step explanation:

Given:

Maximum number of players the soccer team can have = 26

Number of players already chosen by coach = 17

To find how many players can still make the team.

Solution:

Let the players that can still make the team be = $x$

Players already chosen = 17

Total number of players in the team can be given as = $x+17$

Total numbers must not exceed 26.

So, the inequality can be written as:

$x+17\leq 26$

Solving for $x$

Subtracting both sides by 17.

$x+17-17\leq 26-17$

∴ $x\leq 9$

Therefore, no more than 9 players can still make in the soccer team.
