the sum of a number and 19 is at least 8.2.
x+19 >= 8.2
x>-10.8
Isn't it suppose to be x is greater than or equal to 8.2,and the answer would be -10.8.
To solve this inequality, we need to first understand what it means.
The information given states that the sum of a number (let's call it x) and 19 is at least 8.2.
We can represent this inequality mathematically as:
x + 19 ≥ 8.2
To solve for x, we need to isolate it on one side of the inequality sign. We can do this by subtracting 19 from both sides of the inequality.
x + 19 - 19 ≥ 8.2 - 19
Simplifying the expression:
x ≥ 8.2 - 19
Calculating the right side of the inequality:
x ≥ -10.8
Therefore, the solution to the inequality x + 19 ≥ 8.2 is x ≥ -10.8. This means any number that is greater than or equal to -10.8 will satisfy the given inequality.
