Answer:
The value x = 12 is indeed a solution to the inequality 3 + x < 28
Step-by-step explanation:
To determine if x = 12 is a solution of the inequality 3 + x < 28, follow these steps:
Substitute x = 12 into the inequality: 3 + 12 < 28.
Simplify the left side: 15 < 28.
Check if the inequality is true: 15 is indeed less than 28.
Since 15 < 28 is true, x = 12 is a solution of the inequality 3 + x < 28.
Explanation in the context of the number line:
The number line represents the solutions to 3 + x < 28. To find the range of solutions, solve for x:
Subtract 3 from both sides: x < 28 - 3.
Simplify: x < 25.
The number line shows all values less than 25 as solutions to the inequality 3 + x < 28. Since x = 12 is less than 25, it falls within the range of solutions marked on the number line.
Thus, the value x = 12 is indeed a solution to the inequality 3 + x < 28.
Step-by-step explanation: to find if the value of x=12
you can substitute the value of x into the inequality
3+12<28
15<28
the answer is yes x can = 12
