Answer:
Step-by-step explanation:This is a bit tricky, but let's break it down:
"A number" = n (we don't know what the number actually is)
"Twice a number" = 2n (double the number)
"Eight more than twice a number" = 2n + 8 (add 8 to the double of the number)
"Negative eighteen" = -18 (a negative number)
So the statement is: "2n + 8 is greater than -18"
To determine if this statement is true, we need to solve for n: 2n + 8 > -18
Subtract 8 from both sides: 2n > -26
Divide both sides by 2: n > -13
Therefore, the statement is true: "Eight more than twice a number is greater than negative eighteen" when n (the number) is greater than -13.
