4 meters, since 100 centimeters equal 1 meter you'd divide 400 by 4 to get your answer of 4 meters. It's just basic math. Don't get so scared that you'll get your answer wrong and just focus.
-2x
6 - 4 = 2
BOTH NUMBERS HAVE VARIABLE OF X SO THE X WILL GO ON THE 2 ALSO
6x - 4x = 2x
Although the statements are not given, allow me to provide supplements to your understanding of polynomial equations. Because the graphs of two polynomial equations (let's name then f(x) and g(x)), then they do not share coordinate planes or points. If they do not share any points by intersection, then the system of equations does not have a solution. Therefore, Kelly's statement is correct.
Price of apples: 3.50*2=7.00
Price of oranges: 3.50*2=7.00
Price of basket: 6.00
Total:20.00
20.00x=1
x=1/20=0.05
0.05*100=5
The answer is 5%
