Firstly, use the distributive property of multiplication (A(B + C) = A×B + A×C) on -2(q - 5) and -3(q + 1): 
Next, apply the addition property of equality (whatever you add to one side you have to add the same quantity to the other), and add 3q on both sides: 
Lastly, apply the subtraction property of equality (whatever you subtract on one side you have to subtract the same amount on the other side), and subtract 10 on both sides. <u>Your final answer will be 
</u>

72,429 rounded to the nearest ten-thousands is 70,000.
Answer:
The data are at the
<u>Nominal</u> level of measurement.
The given calculation is wrong because average (mean) cannot be calculated for nominal level of measurement.
Step-by-step explanation:
The objective here is to Identify the level of measurement of the data, and explain what is wrong with the given calculation.
a)
The data are at the <u> Nominal </u> level of measurement due to the fact that it portrays the qualitative levels of naming and representing different hierarchies from 100 basketball, 200 basketball, 300 football, 400 anything else
b) We are being informed that, the average (mean) is calculated for 597 respondents and the result is 256.1.
The given calculation is wrong because average (mean) cannot be calculated for nominal level of measurement. At nominal level this type of data set do not measure at all , it is not significant to compute their average (mean).
Answer:
8x + 9
Step-by-step explanation:
Treat the question as 2 separate brackets
First expand 3(2x + 1) :
6x + 3
Then expand 2(x + 3) :
2x + 6
Now add the two answers together and simplify :
= 6x + 3 + 2x + 6
= 8x + 9
hope this helps :)
