If you put them together, +2.5y and -2.5y neutralize themselves while 5x and 3x become 8x.
2.5y + 3x = 27
5x – 2.5y = 5
8x = 32
x = 4
2.5y + 3x4 = 27
2.5y + 12 = 27
2.5y = 27-12
2.5y = 15
y = 15/2.5
y = 6
X = 4
Y = 6
Answer:
x>-28
Step-by-step explanation:
9+x>-19
x>-19-9
Answer:
C.
Step-by-step explanation:
Step-by-step explanation:
Assuming figure to be trapezoid,
Perimeter=6+4+7+4yd
=21 yd
Area of trapezoid=((6+7)/2) x ((4)^2-(0.5)^2)
=(13/2)x(16-0.25)
=6.5 x 15.75
=102.375 Sq yards
