Q. Which expression is equivalent to 92.5+34.6 ?−92.5+34.634.6−92.592.5−(−34.6)−34.6−92.5
Evaluate Original Expression: First, let's evaluate the original expression 92.5+34.6 to know what result we are looking for.Calculation: 92.5+34.6=127.1
Evaluate First Alternative: Now, let's evaluate the first alternative expression −92.5+34.6.Calculation: −92.5+34.6=−57.9This result is not equal to 127.1, so this expression is not equivalent to the original expression.
Evaluate Second Alternative: Next, let's evaluate the second alternative expression 34.6−92.5.Calculation: 34.6−92.5=−57.9This result is also not equal to 127.1, so this expression is not equivalent to the original expression.
Evaluate Third Alternative: Now, let's evaluate the third alternative expression 92.5−(−34.6).Calculation: 92.5−(−34.6)=92.5+34.6=127.1This result is equal to 127.1, so this expression is equivalent to the original expression.
Evaluate Fourth Alternative: Finally, let's evaluate the fourth alternative expression −34.6−92.5.Calculation: −34.6−92.5=−127.1This result is not equal to 127.1, so this expression is not equivalent to the original expression.
