Answer:
52 Empty Seats
Step-by-step explanation:
10 rows of 8 seats would be 10 x 8, which you would get 80. Then you would subtract the amount of people seated in those seats. which is 28
10 x 8 = 80
80 - 28 = 52
There are 52 empty seats left.
This is for the first one 85.714286%
This is for the second one
olution for 21 is what percent of 300
100%/x%=300/21
(100/x)*x=(300/21)*x - we multiply both sides of the equation by x
100=14.2857142857*x - we divide both sides of the equation by (14.2857142857) to get x
100/14.2857142857=x
7=x
x=7
now we have:
21 is 7% of 300
Alright, lets get started.
At the beginning of her training, she is able to run 2 miles without stopping means 2 will be in the addition when we will write the equation for her running miles.
Her goal is to increase her distance by three quarters of a mile each week.
Means in first week, she will add the distance =
miles
Suppose she runs x weeks, so shee will add distance = 
So, suppose she runs total number of miles = d, then

Where d is total numer of miles she runs
x is number of weeks : Answer
Hope it will help :)
