If 7(x+5) = -28 find the value of 6x
elixir [45]
Answer:

-54

Explanation:

First we need to use the distributive property on 7(x+5), so do 7×x + 7×5. Simplify that and you get 7x+35.

Subtract 35 from both sides and you get 7x= -63. Divide both sides by 7 and you get x= -9.

Now we can substitute -9 for x, so do 6×-9 and you get -54.

Hope this helps :)

A lidocaine drip is infusing at 30 mL/hr on an infusion device. The drug is mixed 2g in 500mL D5W. How many mg/minute is the pat
SCORPION-xisa [38]

Answer:

2 mg/minute.

Step-by-step explanation:

We have been given that a drug is mixed 2 g in 500 ml.

First of all, we will convert 2 grams to milligrams. 1 gram equals 1000 milligrams.

2 grams = 2,000 mg.

Now, we will find amount of mg per ml as:

\text{The amount of mg per ml}=\frac{2000\text{ mg}}{\text{500 ml}}

\text{The amount of mg per ml}=\frac{4\text{ mg}}{\text{ml}}

We have been given that a lidocaine drip is infusing at 30 mL/hr on an infusion device, so amount of mg per hr would be:

\text{Amount of mg per hour}=\frac{30\text{ ml}}{\text{ hr}}\times \frac{4\text{ mg}}{\text{ml}}

\text{Amount of mg per hour}=\frac{120\text{ mg}}{\text{ hr}}

We know 1 hour equals 60 minutes.

\text{Amount of mg per hour}=\frac{120\text{ mg}}{\text{ hr}}\times \frac{\text{1 hour}}{\text{60 minutes}}

\text{Amount of mg per hour}=\frac{120\text{ mg}}{\text{60 minutes}}

\text{Amount of mg per hour}=\frac{2\text{ mg}}{\text{minute}}

Therefore, the patient is receiving 2 mg/minute.
