Which of the following statements are true? Select all that apply. The opposite of -3.5 is located 3.5 units to the right of 0 on the number line.
The expression -(-3.5) is equivalent to 3.5.
The opposite of 3.5 is positive.

only the first two are correct (top to bottom)

Step-by-step explanation:

For the first one, we know this because the the opposite of -3.5 is 3.5, and the rightside of zero is positive.

For the second one, we know the expression, -(-3.5) is equal to 3.5 because whenever there is a minus before a parentheses and there's a minus sign inside of the parentheses it automatically becomes positive.

For the third one, we know it's incorrect because the opposite of a positive is a negative.

Lastly, for the last one, (the most bottom one) we know that the opposite of zero is negative zero.
