Answer:
x=10/3, y=4/3. (10/3, 4/3).
Step-by-step explanation:
x-y=2
2x+y=7
-----------
x=y+2
2(y+2)+y=7
2y+4+y=8
3y+4=8
3y=8-4
3y=4
y=4/3
x-4/3=2
x=2+4/3
x=6/3+4/3=10/3
x=10/3, y=4/3.
49.5ft
Step-by-step explanation:

7pi/4 is 7/8 of the entire perimeter. R = 9 ft
the arc length is 7/8 * 2pi*R = 7pi/4 * R = 49.5 ft

Answer:
x = ?
Step-by-step explanation:
Equation written the right way:
d x (3 + x) = kx + 9d (-3 + x) = kx + 9d (-3 + x) = kx + 9
There is no steps or further way to find what x equals.
But above is the right way you should have typed it out and if anyone had figured out the answer, please put it in the comments.
