Answer:

x = 9

Step-by-step explanation:

Given

3 - 4x = - 60 + 3x ( subtract 3x from both sides )

3 - 7x = - 60 ( subtract 3 from both sides )

- 7x = - 63 ( divide both sides by - 7 )

x = 9

Find the missing side length of the right triangle.

Tomtit [17]

This is just some pythagorean theorem, or a^2 + b^2 = c^2. We have a and b, which is 9 and 12, and we need to find c. To find c, we need to first square those, giving u 81 and 144. Now, we need to add them, giving us 225, meaning c^2 = 225. However, we need to find c on its own, so we have to find the square root of 225. That would be 15.

CAN SOMEONE HELP ME !!!!!!!!!

MissTica

Answer:

She will get 80mg of dextromethorphan and 800mg of guaifenesin. And the bottle last for 6 days approximately.

Step-by-step explanation:

Given that the Robitussin DM contains dextromethorphan 10mg/5mL and gualfenesin 100mg/5mL. And we are also given that Mrs Smith took four doses and each dose is 2 teaspoons=2X5=10mL.

So, four doses=4X10=40mL.

So, dextromethorphan in 4 doses is = $\frac{10}{5}X40=80mg$

And Guaifenesin in 4 doses is = $\frac{100}{5}X40=800mg$

Dosage of medicine daily she has to take=40mL and the bottle contains 237 mL. Hence the number of days bottle last = $\frac{237}{40}=5.925$ ≈6 days approximately.
