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

Name the property shown. 4 + 0 = 4 1Commutative Property of Multiplication 2.Identity Property of Addition 3.Commutative Propert
Mars2501 [29]

That is Identity Property of Addition.

Identity Property is a property that states that the sum of any number and zero is always the number you added to zero. This is also the case for multiplication by instead of adding zero, you are multiplying by one.

Hope this helps!
