78 I think because you have to see the other 2 numbers
<span><span>−<span>8<span>x2</span></span></span>+<span>8x</span></span>−<span>64 is the answer
</span>
You multiply the numbers
4X0.55= 2.2
but since you need that 0.2 to complete the self you round up to 3 <span />
The answer is 10 milligrams of Medication A. When you divide 18 by 3 for Medication B, you get 6. Then you have to divide 60 by 6 and you get 10 milligrams.
The probability is one third or 2 sixths.
If you take 6 numbers(like on a number cube) and tai out two of them, you took out 2 out of 6... two sixths.
