Given that she waxes

of the floor in

. Thus in one hour she will wax
Answer: A: (6, 5)
Step-by-step explanation:
When graphing a system of equations, you can find the solution by finding where the graphs intersect. In this case, the graphs intersect at (6, 5).
To verify that this is indeed a solution to the system of equations, we can substitute (6, 5) into both of the given equations:







Since both equations hold true when plugging in the given coordinate (6, 5), we know that this is a solution to the system of equations.
It’s 8 !!!!!!!!!!!!!!!!!!!
Answer:
8 and 17
Step-by-step explanation:
Let the number x and y
Sum of numbers, x + y = 25 -----------( 1 )
One number exceeds other by 9,
that is difference between the numbers is 9, x - y = 9
=> x = 9 + y --------- ( 2 )
Substitute ( 2 ) in ( 1 )
( 9 + y ) + y = 25
2y = 25 - 9
2y = 16
y = 8
Substitute y = 8 in ( 2 ) : x = 9 + y
= 9 + 8 = 17
Therefore the 2 numbers are 8 and 17
