Answer:

-13  2/3

Step-by-step explanation:

1.  6x + 18 = 3x - 23  (Subtract 3x from both sides)

2.  3x + 18 = -23  (Subtract 18 from both sides)

3.  3x = -41  (divide both sides by 3)

4.  x = -13 2/3

Answer:

x = -41/3  (improper fraction)

x = -13 2/3  (mixed number)

Step-by-step explanation:

6x+18=3x−23

Subtract 3x from each side

6x-3x+18=3x-3x−23

3x +18 = -23

Subtract 18 from each side

3x+18-18 = -23-18

3x = -41

3x/3 = -41/3

x = -41/3

x = -13 2/3

Julli [10]

Answer:

3.75 cups

Step-by-step explanation:

Given that :

5 cups of liquid lemonade concentrate is mixed with 2.5 cups of water to make lemonade

Alice is thinking of a number n that she wants her sister to guess. Her first clue is that two less than six times her number is
Alik [6]

Answer:

10 < 6n -2 ≤ 34

n= {3, 4, 5, 6}

Step-by-step explanation:

number

⇒ n

two less than six times the number

⇒ 6n -2

it is between ten and thirty-four (inclusive)

⇒ 10 < 6n -2 ≤ 34

we can solve it as:

  • 10 < 6n -2 ≤ 34     ⇒ add 2 to all sides
  • 12 < 6n ≤ 36          ⇒ divide by 6 all sides
  • 2 < n  ≤ 6
  • n= (2, 6]

or

  • n= {3, 4, 5, 6}
