First step you should do is s<span>implify both sides of your equation:
</span>29-(x+8)=6x-7
Distribute the Negative Sign:
29+-1(x+8)=6x-7
29+-1x+(-1)(8)=6x-7
29+-x+-8=6x-7
29+-x+-8=6x+-7
<span>Combine Like Terms:
</span>(-x)+(29+-8)=6x-7
-x+21=6x-7
<span>Subtract 6x from both sides:
</span>-x+21-6x=6x-7-6x
-7x+21=-7
<span>Subtract 21 from both sides:
</span>-7x+21-21=-7-21
-7x=-28
<span>Divide both sides by -7:
</span>-7x/-7 = -28/-7
And now your answer should be:
x=4

Answer: ($3.055, $3.205)
Step-by-step explanation:
Given : Significance level :
Critical value :
Sample size : n= 36
Sample mean :
Standard deviation :
The confidence interval for population mean is given by :_
Hence, the 95% confidence interval to estimate the population mean = ($3.055, $3.205)
200 centimetes converted to kilometers = 0.002
There are 100 pence in a Pound. So we have to divide 25 pence over this pound, or over 100 pence: 25/100 is 1/4, so 25 Pence is one forth of a Pound (or 25 % in percentages):
The most each dvd can cost is $4.
