r is always less than or equal to 2t - 3 because it's defined as 3 less than twice t. So, B. r ≤ 2t - 3 is the only true statement.
We know that r is 3 less than twice t. We can write this as an equation:
r = 2t - 3
Now, we need to analyze the answer choices to see which one is true based on this equation:
A. r ≥ 2t: This is not always true. For example, if t = 1, then r = 1 (which is less than 2).
B. r ≤ 2t - 3: This is always true. Since r is defined as 3 less than twice t, it will always be less than or equal to 2t - 3.
C. r = t - 3: This is not true. The equation states that r is 3 less than TWICE t, not simply t.
D. r < t - 3: This is not always true. Similar to A, if t = 1, then r = 1, which is not less than t - 3 (which would be -2).
Therefore, the only true statement is:
B. r ≤ 2t - 3.
This statement holds true regardless of the value of t.
Complete question should be:
If r is 3 less than twice t, which of the following is true?
A. r ≥ 2t
B. r ≤ 2t - 3
C. r = t - 3
D. r < t - 3
