Which expression is equivalent to -8.2-5 ? Choose 1 answer: (A) 8.2-5 (B) -8.2+(-5) (c) -8.2+5 (D) 5-(-8.2)

Understand the problem: Understand the problem. We need to find an expression that is equivalent to the given expression -8.2 - 5.Analyze the choices: Analyze the choices. (A) 8.2 - 5 changes the sign of the first term, which is not equivalent. (B) -8.2 + (-5) is the same as -8.2 - 5 because adding a negative is the same as subtracting. (C) -8.2 + 5 changes the second term to positive, which is not equivalent. (D) 5 - (-8.2) is the same as 5 + 8.2, which changes both the order and the signs, so it is not equivalent.Choose the correct answer: Choose the correct answer. The expression that is equivalent to -8.2 - 5 is -8.2 + (-5), because adding a negative number is the same as subtracting that number.
