To solve an absolute inequality first step is to isolate absolute value expression.
Hence remove -4 from the left side. So, add 4 to each sides of the inequality.
2|x + 7|−4 ≥ 0
2|x + 7|−4 +4≥ 0 +4
2|x + 7| ≥ 4 Combine the like terms.
Divide each sides by 2.
|x + 7| ≥2
Next step is to remove the absolute value sign. So,
x + 7≥2 and x+7≤-2.
x≥2-7 and x≤-2-7
x≥-5 and x≤-9
So, the correct choice is C. {x | x ≤ -9 or x ≥ -5}.
Add the numbers: 57 + 39 + 76 + 87 + 91 = 350;
Divide by how many numbers (i.e. we added 5 numbers): 350 ÷ 5 = 70;
<span>So the average is 70;</span>
According to the given data we have the following:
what does 68.47 + 75.20 + 60.05 equal to
So, in order to calculate this, first we would sum the decimals of this numbers as follows:
0.47+0.20+0.05=0.72
Then procees to sum the numbers 68+75+60
So, 68+75+60=203
Therefore, 203+0.72=203.72
So, 68.47 + 75.20 + 60.05 equal to 203.72
Total people=180
discount received people=25%+10%=35%
People who did not receive discount=100-35%=65%
65%of 180=65×180/100=117
So 117 people did not receive discount
