One number is 4 times as large another. The sum of their reciprocals is 45/4. Find the two numbers
Reptile [31]
Let, 
the numbers be "x" and "y"
According to the question,
x = 4y ......................................................equation (1)

\frac{1}{x} + \frac{1}{y}= \frac{45}{4}...................................equation (2)

Taking equation (2)
\frac{1}{x} + \frac{1}{y}= \frac{45}{4}

Substituting the value of "x" from equation (1), we get,

\frac{1}{(4y)} + \frac{1}{y}= \frac{45}{4}

\frac{1}{4y} + \frac{1}{y}* \frac{4}{4} = \frac{45}{4}

\frac{1}{4y} + \frac{4}{4y}= \frac{45}{4}

\frac{1+4}{4y} = \frac{45}{4}

\frac{5}{4y} = \frac{45}{4}

Cross multiplying, we get,

5*4 = 45*4y

20 = 180y
<u />
\frac{20}{180}  = y

\frac{1}{9}  = y

y =  \frac{1}{9}

Now,
Taking equation (1)
x = 4y
Substituting the value of "y", we get

x = 4( \frac{1}{9} )

x= \frac{4}{9}

So, the numbers are \frac{1}{9} and \frac{4}{9}

Nick bought t candies and divided them equally between his y friends and me. Each of us got 7 candies.
inysia [295]
<h2>Hello!</h2><h2>Let me help you.</h2>

As I understand, you need to write an equation that relates t \ and \ y. This problem will be solved using equations. The problem states:

<em>Nick bought t candies and divided them equally between his y friends and me. Each of us got 7 candies.</em>

<em />

From this statement, we know that:

t: Number of candies Nick bought.

y: Number of friends.

Since I am included in this problem, the number of people involved here can be expressed as:

y+1

Since each of us got 7 candies, then it is true that:

\frac{t}{y+1}=7 \\ \\ t=7(y+1)

<em>So t (number of candies) is a function of y(number of friends).</em>

If f(X+4) =3x+4 , then find the value of f(4) <br>please explain it clearly .​
Paul [167]

\\ \sf\longmapsto f(x+4)=3x+4

\\ \sf\longmapsto f(x)=3x+4-4

\\ \sf\longmapsto f(x)=3x

Now

\\ \sf\longmapsto f(4)

\\ \sf\longmapsto 3(4)

\\ \sf\longmapsto 12
