Sophia has an ear infection. The doctor prescribes a course of antibiotics. Sophia is told to take 500 mg doses of the antibioti
olganol [36]

Answer:

Dosage= 500 mg

Frequency= twice a day (every 12 hours)

Duration= 10 days

Number of dosage= 10*2= 20

residual drug amount after each dosage= 4.5%

We can build an equation to calculate residual drug amount:

  • d= 500*(4.5/100)*t= 22.5t, where d- is residual drug, t is number of dosage
  • After first dose residual drug amount is: d= 500*0.045= 22.5 mg
  • After second dose: d= 22.5*2= 45 mg

As per the equation, the higher the t, the greater the residual drug amount in the body.

Maximum drug will be in the body:

  • d= 20*22.5= 450 mg at the end of 10 days

Maximum drug will be in the body right after the last dose, when the amount will be:

  • 500+19*22.5= 927.5 mg

5x + 3 = 7x – 1. Find x<br><br> a. 1/3<br> b. ½<br> c. 1<br> d. 2
weqwewe [10]

Answer:

Step-by-step explanation:

First you need to get like items on the same side(put the variables on one side and the non-variables on the other).  Remember anything you do on one side of the equal, you have to do on the other side, too.

5X+3=7X-1   I'm going to move the -1 first, but you don't have to as long as you keep the equation equal.

5X+3+1=7X-1+1    We know that +1-1 is zero and so is -1+1.  So

5X+3+1=7X      We don't need to keep that zero.

5X+4=7X         Now, we want to move the 5X over.

5X-5X+4=7X-5X    Simplify and get rid of the zero.

4=2X             Last, we have to divide to get the 2 away from the X.

4/2=2X/2            Not everyone know that slash mean divide, :-).

2=X
