If a physician order is 25% dextrose 1000 mL and all you have is 70% dextrose 1000 mL and 5% dextrose how much 70% dextrose will
miskamm [114]

Answer:

The answer is below

Step-by-step explanation:

Since 1000ml Of Dextrose 25% is needed to be produced from Dextrose 70%. Let us assume that x ml of Dextrose 70% is mixed with a Dextrose 5% to get 1000 ml of Dextrose 25%. Hence:

The amount of Dextrose 5% = 1000 ml - x ml = 1000 - x

25% of 1000 ml = 70% of x + 5% of (1000 - x)

25000 = 70x + 5000 - 5x

Simplifying gives:

65x = 25000 - 5000

65x = 20000

x = 308 ml

Therefore 308 ml of Dextrose 70% was mixed with 692 ml of Dextrose 5% to produce 1000 ml of Dextrose 25%.

Please HELPPPPP!!! <br><br> I DONT KNOW WHY IM GETTING THEM WRONG
Nady [450]

Answer:

n = -33

Step-by-step explanation:

Let n = number

Sum of a number and 9

(n+9)

is tripled

3(n+9)

the result is six less then twice the number

2n-6

3(n+9) = 2n-6

Distribute

3n+27 = 2n-6

Subtract 2n from each side

3n-2n +27 = -6

n +27 = -6

Subtract 27 from each side

n+27-27 = -6-27

n =-33
