Eight and six tenths in decimal form is 8.6
Answer:
12
Step-by-step explanation:
To solve this problem, all we need is the conversion
factor.
We know that there are:
1 liter = 202.884 teaspoons
Therefore the mass of Phenobarbital is:
mass = (2 grams / 1 Liter) * (1 teaspoon) * (1 Liter /
202.884 teaspoons)
<span>mass = 0.00986 g = 9.86 x 10^-3 g = 9.86 mg</span>

Solve the second equation for y

Substitute the given value of y into the first equation

Solve the equation for x

Substitute the given value of x into the second equation

Solve the equation for y

The possible solution of the system is the ordered pair (x,y)
