No. 3x - 4y = -6 is not equal to 6x - 8y = 12. If you multiplied the first equation by 2, it would be 6x - 8y = -12, not 6x - 8y = 12. As for the second pair, if you multiply 2x + 5y = 1 by 3, it would be 6x + 15 = 3. So the second pair are equal.

The woman is moving at 6mi/hr which means 1mi per 10 minuets because 1 hour = 60 minuets and she is moving 6 mi every 60 minutes which means 1 mi every 10 minuets , same thing for that man 12 mi every hour = 2 mi every 10 minuets , and because of the opposite direction we will add 2 + 1 = 3mi after 10 minuets. I hope that helped u a little bit.

The client is to receive cyclophosphamide (Cytoxan) 50 mg/kg intravenously in divided doses over 5 days. The client weighs 176 p
marishachu [46]

Answer:

800 mg

Step-by-step explanation:

As the excerpt states that the client weights 176 pounds and is to receive cyclophosphamide (Cytoxan) 50 mg/kg, we have to convert 176 pounds to kg:

1 kg → 2.20 pounds

  x   ←  176 pounds

x= (176 pounds * 1 kg)/2.20 pounds= 80 kg

Now, we have to determine the total amount of cyclophosphamide (Cytoxan) that the client has to receive:

50 mg/kg

For 80 kg: 80 kg *50 mg/kg= 4,000  mg

As the dose is divided over 5 days:

4,000 mg / 5= 800 mg

The client will receive 800 mg of cyclophosphamide each day.

Ursula bought 9 dozen rolls of first aid tape for the health office. The rolls were divide equally into 4 boxes. How many rolls
vredina [299]
We know that 12 equals one dozen. It is not asking for a dozen, but for 9 dozen. So, we need to multiply 9 by 12. 9*12 = 108. 

It says the rolls of first aid tape were divided equally into 4 boxes. We need to divide these 108 rolls into 4 equal groups, since that is what took place in the problem. So, we divide 108 by 4. 
108/4 = 27. There are 27 rolls in each box.
