Answer:
8x+1
Step-by-step explanation:
4(x-1) + (x+2) + 3(x+1)
4x-4 + x+2 + 3x+3
combine all x
4x+x+3x= 8x
combine all numbers without variables
(-4) + 2+3=1
8x+1
Answer:
180.4 inches (15.033 feet)
Step-by-step explanation:
To solve this, we convert 15.3 feet to inches. We do this by multiplying 15.3 by 12. This gets us 183.6. Now, we subtract 3.2 from 183.6. This gets us 180.4. That means the piece cut off of 180.4 inches long. To convert this to feet, we divide by 12. That gets us 15.033. That means the piece cut off is 180.4 inches long, or 15.033 feet long.
Answer:
10.89%
Step-by-step explanation:
Data provided in the question:
Number of economist in the panel = 68
Unemployment Rate, % : 10.2 10.4 10.6 10.8 11.0 11.2 11.4
Economists : 2 4 7 24 14 12 5
Now,
The average unemployment rate to be next year will be calculated using weighted average as:
= 
or
= 
or
= 
or
= 
or
= 10.89%
Hence,
The expected average unemployment rate to be next year by the panel will be 10.89%
Answer:
A. a. 9x^4 b. 3x^5y
Step-by-step explanation:
a. 5x^4 + 4x^4
Since these are to the same power, they are like terms and we can add them
9x^4
b. 12x^5y − 9x^5y
Since these are to the same power, they are like terms and we can subtract them.
3x^5y
