Solve by substitution or elimination;<br><br> x+2y=-1<br> x-y=5

Strike441 [17]

I would love to use substitution (It is simplier that way I guess)

solve your system of equations.

x+2y=−1;x−y=5

Solve x+2y=−1 for x:

x+2y+−2y=−1+−2y(Add -2y to both sides)

x=−2y−1

Substitute (−2y−1) for x in x−y=5:

x−y=5

−2y−1−y=5

−3y−1=5(Simplify both sides of the equation)

−3y−1+1=5+1(Add 1 to both sides)

−3y=6

−3y/−3 = 6/−3(Divide both sides by -3)

y=−2

Substitute (−2) for y in x=−2y−1:

x=−2y−1

x=(−2)(−2)−1

x=3(Simplify both sides of the equation)

So the answer is (x = 3 and y = -2)

Given the following prescription formula, what is the ratio strength (nearest whole number) of methylcellulose in the finished p

Mamont248 [21]

Answer:

147

Step-by-step explanation:

Given:

Progesterone = 3.8 g

Glycerin = 7 mL

2% methylcellulose solution 50 mL

Cherry syrup ad = 90 mL

Now,

The total volume of the solution = 7 + 50 + 90 = 147 mL

Also,

2% methylcellulose solution 50 mL is concluded as:

the volume of methylcellulose in the solution is 2% of the total volume of the solution

thus,

volume of methylcellulose = 0.02 × 50 mL = 1 mL

Therefore,

Ratio strength of methylcellulose in the finished product

= $\frac{\textup{volume of methylcellulose}}{\textup{ total volume of the solution}}$

= $\frac{\etxtup{1}}{\textup{ 147}}$

Hence, the answer according to the question is 147
