Ten (10) times (multiplication) the sum (addition) of half (

a number (n) and 6 is (=) 8.
10(
+ 6) = 8 Use the Distributive Property
5n + 60 = 8 Subtract 60 from both sides
5n = -52 Divide both sides by 5
n = -10
Answer:
$9.56
Step-by-step explanation:
$13.00 x .30 = 3.90
13.00 - 3.90 = $9.10 x .05 = 0.46
$9.10 + 0.46 = 9.56
Answer:
16%
Step-by-step explanation:
The mean is $15 and the standar deviation is $3.
mean = 15 and SD = 3
We need to find percentage less than 12 per hour
P(x<12)= P(x=12)
to find P(x=12) we find z-score

Now use z-score table . z-score = 0.1587
P(x=12)=0.1587
To get percentage we multiply by 100
0.1587 * 100 = 15.87 = 16%
