Answer: 42.9%
Step-by-step explanation:
Percent error is the difference between the measured and known value, which is divided by the known value, and then multiplied by 100%.
Percent error = (Estimated number- Actual number)/Actual Number × 100.
= (60 - 42)/42 × 100
= 18/42 × 100
= 0.429 × 100
= 42.9%
Answer:
What was the original number??
Step-by-step explanation:
= -9(x – 4) – 6x
Multiply -9 by everything in parentheses first
= (-9*x) + (-9*-4) - 6x
= -9x + (36) - 6x
Combine like terms
= (-9x-6x) + 36
= -15x + 36
The middle choice is the answer:
-15x + 36
Hope this helps! :)
