Simplify 3 (x+2)- x + 8

First you must distribute the 3 to the numbers inside the parentheses, which would be x and 2...

(3 * x) + (3 * 2) - x + 8

3x + 6 - x + 8

Now you must combine like terms. This means that first numbers with no variables go together. Then the numbers with the same variables must be combined...

no variable combination:

3x + 6 -x + 8

6 + 8 = 14

3x - x + 14

same variable combination:

3x - x + 14

3x - x = 2x

2x + 14

Hope this helped!

Using the properties of inequalities, write down the inequality that you will get if you: add the number –5; 2.7; 7; to both sid
puteri [66]

Answer:

See below

Step-by-step explanation:

1..........................

  • 18 >−7

Add –5; 2.7; 7 to both sides

  • 18 -5 > -7 - 5 ⇒ 13 > -12
  • 18 + 2.7 > - 7 + 2.7 ⇒ 20.7 > - 43
  • 18 + 7 > -7 + 7 ⇒ 25 > 0

2..........................

  • 5 > -3

Subtract 2; 12; -5 from both sides

  • 5 - 2 > -3 -2 ⇒ 3 > - 5
  • 5 - 12 > -3 - 12 ⇒ -7 > -15
  • 5 -(-5) > -3 - (-5) ⇒ 10 > 2

3..........................

  • - 9 < -6

Multiply both sides by 3; −3; −1

<em>When multiplying both sides of inequality by positive number the sign stays as is, when multiplying both sides of inequality by negative number the sign reverses</em>

  • -9 *3 < -6*3 ⇒ -27 < - 18
  • -9*(-3) > -6*(-3) ⇒ 27 > 18
  • -9*(-1) > -6*(-1) ⇒ 9 > 6
