Answer:
Step-by-step explanation:
To find the average of 4 things, we add those four things together and divide by 4. So, here we need to do the opposite. Since the last thing we would do to find the average is divide by four, we are going to start there and do the opposite. The average is 166. So...
166X4=664
Now instead of adding, we will subtract the three that we know, leaving the fourth. 664-200=464 464-150=314 314-180=134
So the weight of the fourth person is 134 pounds.
If you would like to know 55 percent of what number is 495, you can calculate this using the following steps:
55% of what number = 495
55% * x = 495
55/100 * x = 495
x = 495 * 100/55
x = 900
The number you are looking for is 900.
The answer is B. I did the test and i got it right
Answer : x^2 - 4x^2 - 2x^2 + 3
