To determine which of the options is equivalent to 185, let's evaluate each one.
-
85 8: This seems to be a typo or incorrect formatting.
-
8−5 8: Assuming this means \( 8 - 5 \times 8 \): \[ 8 - 5 \times 8 = 8 - 40 = -32 \]
-
815 8: This is also unclear but could be interpreted as just the number 815, which is not equal to 185.
-
5−8: This equals: \[ 5 - 8 = -3 \]
None of the options clearly result in 185 based on the interpretations above. If the response format is incorrect, please provide more clarity on the options given for a more accurate assessment.
