Let x be the number of pounds of beans that sells for $0.72 used and y
be the number of pounds of beans that sells for $0.52 used. Then:
x + y = 110 . . . (1)
0.72x + 0.52y = 81.4 . . . (2)
From (1), x = 110 - y . . . (3)
Putting (3) into (2) gives
0.72(110 - y) + 0.52y = 81.4
79.2 - 0.72y + 0.52y = 81.4
79.2 - 0.2y = 81.4
0.2y = 79.2 - 81.4 = -2.2
y = -2.2/0.2 = -11
x = 110 - (-11) = 110 + 11 = 121
The solution is not reasonable because, there cannot be negative value for the number of pounds of beans used.
And 121 pounds of beans cannot produce 110 pounds.

The angle appears to be less than 90 degrees making it an acute angle. Angles above 90 degrees are obtuse angles.
Answer:
y/7 =2/x does not show direct variation
Step-by-step explanation:
y/7 =2/x is one equation, so please ask, "Does y/7 =2/x represent direct variation?"
Let's solve this y/7 =2/x for y: Mult. both terms by 7.
We obtain y = 14/x. This does NOT have the form of a direct proportion because that x is in the denominator.
So, no, y/7 =2/x does not show direct variation.
