Question 2

Answer 1

The expression equivalent to (-7) – 2 is 7 - (-2), which applies the rule of changing a subtraction to the addition of a negative number.

Step-by-step explanation:

Understanding Expressions

Let's examine the given expressions to find one equivalent to (-7) – 2. Recall the rule that when subtracting, you change the sign of the number being subtracted, so the expression (-7) - 2 becomes (-7) + (-2). This is because subtracting a positive is the same as adding its negative equivalent.

Now let's review the provided options:

(-7)+2 does not equal (-7) - 2 because adding a positive number is not the same as adding a negative.

7 - (-2) does equal (-7) - 2. Here, we are subtracting a negative, which is equivalent to adding the positive of that number.

7+(-2) is not the same because here we have a positive 7, not a negative.

(-7)+(-2) is also not the same, as this is just adding two negative numbers together, not subtracting.

Therefore, the expression with the same value as (-7) – 2 is 7 - (-2).

Answer 2

(-7)+(-2)

Step-by-step explanation:

Which other expression has the same value as (-7) – 2?

The expression given :

(-7) – 2 = - 7 - 2 = - 9

To obtain our answer, we find the result of the expressions given in the option :

(-7)+2 = - 7 + 2 = - 5

7- (-2) = 7 - - 2 = 7 + 2 = 9

7+(-2) = 7 - 2 = 5

(-7)+(-2) = - 7 + - 2 = - 7 - 2 = - 9

Only option D gives the same result as the result of the expression given ; hence, our answer is option D
