Answer:
Step-by-step explanation:
We have the equation:
Let's simplify this a bit. Let . Then . We can substitute the exponents:
Use the properties of exponents, we can write . We can do the same thing on the right. So:
We can now factor out a from the left and a on the right. This yields:
Evaluate the expressions within the parentheses:
Evaluate:
Now, let's multiply both sides by . So:
Also, let's divide both sides by . Multiply on the right:
Therefore:
We can now substitute back u. Notice that 27 is the same as 3 cubed and 1000 is the same as 10 cubed. So:
Since they have the same base, their exponents must be equal. Therefore:
Add 2 to both sides:
So, the value of x is 5.
And we're done!
<span>Let's start with basic definitions:
1 inch-----0.0833333 ft
If 0.375 Ft- represents 0.25 inches
then 1 foof-x inches
0.25 inches x 1 ft / 0.375 ft: 0.66666666666667 (2/3) inch
1 foot is represented by 2/3 of an inch</span>

Answer:
First you need to convert pounds to kilograms. 196 pounds is 88.904 kilograms. The directions tell you that 20 milligrams of the drug is to be administered for each kilogram of a person's weight.
You need to multiply 88.904 by 20. That should give you 1778.08 milligrams of lincomycin.
You would then mix 250 cc's of saline solution to the 1778.08 milligrams of lincomycin; but I think its just asking you how much lincomycin to administer.
