"the sum of three and a number," expressed algebraically, is "3+x," where x represents the unknown number.  Adding this to 24 results in 3+x+24.
Can you simplify this?  Note:  You can NOT solve for x.  Just simplify.

Answer:

n > 10

n < 9

Interval notation:

(-∞, 9) U (10, ∞)

Step-by-step explanation:

2n + 7 > 27 or 3 + 3n < 30

     -7     -7      -3             -3

2n > 20                 3n < 27

÷2    ÷2                ÷3     ÷3

n > 10                      n < 9

<---------            ----------->

-2(3x+2) is greater than or equal to -6x-4
olchik [2.2K]
The inequality would look like this:

-2 (3x + 2)\geq-6x-4

To begin to find the solutions, distribute the -2 throughout the set of parenthesis on the left side of the inequality by multiplying the -2 by each term in the set of parenthesis

-2 x 3x = -6x
-2 x 2 = -4

-6x -4 \geq-6x-4

Begin to isolate x by performing the opposite operation of adding -6x on both sides of the inequality

0x -4 \geq-4

Next perform the opposite operation by adding 4 on both sides of the inequality

0x \geq 0

Now, I'm not exactly understanding how that can possibly work. So, I guess I didn't really help you. But add a comment so that we can talk about the problem :)
