Final answer:
After evaluating each statement, we find that B and D are true, while A and C are false. Statement A incorrectly suggests 18 is less than 1.8, and statement C wrongly claims the sum of 18 plus 18 equals 72.
Step-by-step explanation:
Let's examine each statement to determine if it is true or false:
- A. 18<1.8 is false because 18 is greater than 1.8.
- B. 0.19−5<18 is true. When you subtract 5 from 0.19, you get a number that is less than 18.
- C. 18+18=72 is false. The correct sum is 18+18=36.
- D. 13≤18 is true because 13 is less than or equal to 18.
After evaluating each option:
- The statement A is false because the inequality sign is incorrect; 18 is actually greater than 1.8.
- Statement B is true; 0.19 minus 5 would result in a negative number, which certainly is less than 18.
- The claim in statement C is false; this is a simple arithmetic error, and correcting it shows that the sum of 18 and 18 is 36, not 72.
- Finally, statement D is true, correctly indicating that 13 is less than or equal to 18.
