Answer:
We'll be making 35 liters of 19% glucose.
How much of a 15% solution and a 35% solution do we mix in order to get 35 liters of a 19% glucose solution?
X = liters of 15% and Y = liters of 35%
(.15 X + .35 Y) / 35 = .19
The number of Y liters will equal (35 -X) so the equation becomes
(.15 X + .35 *(35-X) ) / 35 = .19
(.15X + 12.25 -.35X) / 35 = .19
(-.20 X / 35) + (12.25 / 35) = .19
(-.20 X / 35) + .35 = .19
(-.20 X / 35) = -.16
-.20X = -5.6
X = 28 liters of 15% and
Y = 7 liters of 35% glucose
Answer is "c" 28 liters

Answer:
X=37/20
Explanation:
In a kite, one of the diagonals will bisect the other. So, 2(PT)=PR
By substitution, this becomes the equation
2(10x-1)=35
20x-2=35
20x=37
x=37/20

Answer:
Angle TQR is 52 degrees
Explanation:
A kite only bisects one set of opposite angles, so angle TQR is congruent to angle TQP. To find angle TQP use this equation:
Angle TPQ+Angle TQP=90
This is possible because angle QTP is right(diagonals of kites are perpendicular) and because all triangles have interior angles that add up to 180 degrees. The remaining amount of degrees apart from the right angle should be 90 degrees(180-90=90).
Substitute:
38+ angle TQP= 90
Angle TQP= 52 degrees
Angle TQP is congruent to angle TQR, so
Angle TQR=52 degrees
