Question

Which of the following statements is false?

a) -5 = -5
b) 4-5 = 5
c) --5
d) -515

Answer 1

The false statement in the options provided is b) 4-5 = 5. The correct calculation for 4 minus 5 is -1, not 5. Therefore, the revised statement is 4-5 = -1.

Step-by-step explanation:

The question asks which of the following statements is false: a) -5 = -5, b) 4-5 = 5, c) --5, or d) -5/15. To answer this, we will assess each statement.

• Statement a) is true because a number is always equal to itself.
• Statement b) is false because 4 minus 5 would result in -1, not 5. Therefore, the correct statement is 4-5 = -1.
• Statement c) appears incomplete or unclear as written. The double negative '--' usually means 'plus', so if this is --5, it would be equivalent to +5 which is true.
• Statement d) is true if we interpret it as '-(5/15)', which simplifies to -1/3.

According to the evaluation above, the false statement among the options provided is b) 4-5 = 5.
