Arman, Narek and Areg are brothers. Arman's age is five times as much as Areg's age and Narek is 12 years elder than Areg. If Na
Bumek [7]
Armans age : x
Aregs age: y

X = 5y
(15 - 12) = y. They said narek is 12 years older than areg so you deduct 12 years from nareks age which is 15.

So therefore y = 3. So Areg is 3 years old.

Since we know that y = 3
X = 5(3)
X = 15

So therefore Arman is 15 years and Areg is 3 years.

The speed of an elevator varies inversely with the weight it carries. If the elevator rises at 10 feet per second when it carrie
777dan777 [17]

Answer:

8\frac{ft}{sec}

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form y*x=k or y=k/x

Let

x-----> the speed of the elevator

y----> the weight it carries

so

y*x=k

<em>Find the constant k</em>

For x=10 ft/sec, y=400 lb

substitute

k=10*400=4,000

The equation is

y*x=4,000

Find the speed for y=500 lb

substitute in the equation

500*x=4,000

x=4,000/500=8\frac{ft}{sec}
