The polynomial abcd + e - fg + h2 has four terms.
in short, 25% is just 1/4 of anything, we know she's sold 25% which is $600, so her daily goal must be 1/4 + 1/4 + 1/4 + 1/4, or namely 600 + 600 + 600 + 600 = 2400.
When 2 lines are coinciding, this means its the same line.
One equation is simply a multiple of the other.
8x = 4x*2
This means the multiplier is 2
5y*2 = 10y
8*2 = 16
The missing values are 10y and 16
We are required to convert the speed from miles per hour to miles per minute;
speed of the car=50 mph
the speed in miles per minute will be as follows;
1 hr=60 min
thus the speed will be given by:
speed=distance/time
=(50 miles)/(1 hours)
=(50 miles)/(60 min)
=5/6 m/min
thus the distance traveled in 10 min will be:
distance=speed*time
=5/6*10
=8 1/3 miles
I believe that the answer is 12.5%
Reason 100% of 80= 80,
So if 80=100%,
then that means 10=x%
Fore it means that, 
%=12.5%
