Question

7. Indicate whether each expression is equivalent to -10, equivalent to 10, or not equivalent

to -10 or 10.
Expression
7+3
-7+(-3)
7+(-3)
-2 × (-5)
-2x5
2× (-5)
Equivalent to -10
Equivalent to 10
Not Equivalent to
-10 or 10

Answer 1

Let's evaluate each expression:

7 + 3 = 10 (Equivalent to 10)

-7 + (-3) = -10 (Equivalent to -10)

7 + (-3) = 4 (Not Equivalent to -10 or 10)

-2 × (-5) = 10 (Equivalent to 10)

-2x5 = -10 (Equivalent to -10)

2 × (-5) = -10 (Equivalent to -10)

So, here are the results:

Equivalent to -10: -7 + (-3), -2 × (-5), 2 × (-5)

Equivalent to 10: 7 + 3, -2x5

Not Equivalent to -10 or 10: 7 + (-3)
