Answer:
x + y = 9.
Step-by-step explanation:
xy = 2(x + y)
xy = 6(x - y)
2x + 2y = 6x - 6y
8y = 4x
x = 2y
Substitute for x in the first equation:
2y^2 = 2(2y + y)
2y^2 = 6y
y^2 = 3y
y(y - 3) = 0
y = 0, 3.
x = 2y = 0 , 6.
As the integers are positive they must be 3 and 6.
x + y = 3+6 = 9.
Answer:
1,187.5
Step-by-step explanation:
Convert inch to feet or convert feet to inch. Convert inch to feet by:
Calculate the inch by subtracting it from the same amount of length(12) and multiplying it by 100
6/1 divided by 3/8
6/1 x 8/3
if you cross multiply, 2 can go into 6 and 8
6 divided 2 is 3
8 divided 2 is 4
so
6/1 would be 3/1
8/3 would be 4/3
3/1 x 4/3 = 12/3
12/3 simplified is 4
Use the formula y2-y1/x2-x1 and sub in the points
Hope this helps
