Which expression is equivalent to -55.7+(-83.8) ? -83.8-55.7 -83.8-(-55.7) -55.7+83.8 -55.7-(-83.8)

Understand Given Expression: First, let's understand the given expression -55.7 + (-83.8). This is a sum of two negative numbers.Calculate Magnitudes: When we add two negative numbers, the result is also negative, and the magnitude of the result is the sum of the magnitudes of the two numbers. So, -55.7 + (-83.8) = -(55.7 + 83.8).Find Equivalent Expression: Now, let's calculate the sum of the magnitudes: 55.7 + 83.8. 55.7 + 83.8 = 139.5Therefore, the original expression -55.7 + (-83.8) is equivalent to -139.5.Now, let's examine the options given to find the equivalent expression: -83.8 - 55.7 would result in a negative number, but it's not the same as adding two negative numbers. -83.8 - (-55.7) would result in subtracting a negative, which is the same as adding a positive, so this is not equivalent. -55.7 + 83.8 would result in adding a negative number to a positive number, which is not the case here. -55.7 - (-83.8) is equivalent to -55.7 + 83.8, which is the same as subtracting a negative, meaning we add the positive value of that number. This is the correct equivalent expression.The correct equivalent expression to -55.7 + (-83.8) is -55.7 - (-83.8).

Understand Given Expression: First, let's understand the given expression $-55.7 + (-83.8)$ . This is a sum of two negative numbers.
Calculate Magnitudes: When we add two negative numbers, the result is also negative, and the magnitude of the result is the sum of the magnitudes of the two numbers. $\newline$ So, $-55.7 + (-83.8) = -(55.7 + 83.8)$ .
Find Equivalent Expression: Now, let's calculate the sum of the magnitudes: $55.7 + 83.8$ . $\newline$ $55.7 + 83.8 = 139.5$
Find Equivalent Expression: Now, let's calculate the sum of the magnitudes: $55.7 + 83.8$ . $\newline$ $55.7 + 83.8 = 139.5$ Therefore, the original expression $-55.7 + (-83.8)$ is equivalent to $-139.5$ .
Find Equivalent Expression: Now, let's calculate the sum of the magnitudes: $55.7 + 83.8$ . $55.7 + 83.8 = 139.5$ Therefore, the original expression $-55.7 + (-83.8)$ is equivalent to $-139.5$ . Now, let's examine the options given to find the equivalent expression: $-83.8 - 55.7$ would result in a negative number, but it's not the same as adding two negative numbers. $-83.8 - (-55.7)$ would result in subtracting a negative, which is the same as adding a positive, so this is not equivalent. $-55.7 + 83.8$ would result in adding a negative number to a positive number, which is not the case here. $-55.7 - (-83.8)$ is equivalent to $-55.7 + 83.8$ , which is the same as subtracting a negative, meaning we add the positive value of that number. This is the correct equivalent expression.
Find Equivalent Expression: Now, let's calculate the sum of the magnitudes: $55.7 + 83.8$ . $55.7 + 83.8 = 139.5$ Therefore, the original expression $-55.7 + (-83.8)$ is equivalent to $-139.5$ . Now, let's examine the options given to find the equivalent expression: $-83.8 - 55.7$ would result in a negative number, but it's not the same as adding two negative numbers. $-83.8 - (-55.7)$ would result in subtracting a negative, which is the same as adding a positive, so this is not equivalent. $-55.7 + 83.8$ would result in adding a negative number to a positive number, which is not the case here. $-55.7 - (-83.8)$ is equivalent to $-55.7 + 83.8$ , which is the same as subtracting a negative, meaning we add the positive value of that number. This is the correct equivalent expression. The correct equivalent expression to $-55.7 + (-83.8)$ is $-55.7 - (-83.8)$ .
