Answer:
Explanation:
Let's break this problem down step by step.
Start by defining a variable to represent the unknown number. Let's call it "x".
Translate the given sentence into an inequality:
"The sum of a number and 19" means "x + 19"
"is at least" means "≥"
"8.2" means "8.2"
So the inequality is:
x + 19 ≥ 8.2
Solve the inequality for x:
x + 19 ≥ 8.2
Subtract 19 from both sides:
x ≥ 8.2 - 19
Simplify:
x ≥ -10.8
So the solution is:
x ≥ -10.8
This means that any number that is greater than or equal to -10.8 will make the original sentence true.
