Answer:
C
Step-by-step explanation:
It should be because of the fact that you know a square is a rectangle, a square is a rhombus, and a rectangle is a parallelogram.
x=9, y=10. (9, 10). The two numbers are 9 and 10.
3x+5y=77
x+y=19
------------------
-3(x+y)=-3(19)
---------------------
-3x-3y=-57
-------------------
2y=20
y=20/2
y=10
x+10=19
x=19-10
x=9
The point of intersection
(0,-14,22/5), (2,0,24/5), (-22,-24,0).

Answer: 17.5
7:10 = x:25
times both sides by 25
25(7/10) =x
than solve for x
X = 25 × (7/10)
X = 17.5
