Answer 1

Answer:

Step-by-step explanation:

3x + 2 < 12

3x < 10

x < 10/3

x < 3 1/3

D. x = 3.5, because 3.5 > 3 1/3 and x can't be bigger than 3 1/3

Step-by-step explanation:

3 x + 2 < 12

( -2 from both sides )

3 x < 10

( ÷ 3 from both sides )

x < 3.33333333333

So x is less than 3.33333333333 but the question asks which is not a solution and 3.5 is greater than 3.33333333333 so 3.5 is your answer
