The age of Sita is five years more than Gautam's age. 5 years ago, the ratio of their ages was 3:2. Find their present ages.

vampirchik [111]

<h2>Question:-</h2>

The age of Sita is five years more than Gautam's age. 5 years ago, the ratio of their ages was 3:2. Find their present ages.

<h2>Solution:-</h2>

The age of Sita = (x + 5) years.

And, the age of Gautam = x years.

Now,

5 years ago, the ratio of their ages was 3 : 2

$\therefore$ $\bf \frac{3}{2} \: = \frac{x \: + \: 5}{x}$

Now by cross multiplying, we get,

3x = 2(x + 5)

3x = 2x + 10

3x - 2x = 10

Hence, the age of Sita = (x + 5) = (10 + 5) = 15 years.

And, the age of Gautam = x = 10 years.

Now,

The present age of Sita = 15 + 5 = 20 years. (Answer)

And, the present age of Gautam = 10 + 5 = 15 years. (Answer)

I do not know how the 1's cancel out to give 1/3^x

muminat

Unfortunately your teacher is using x as both a variable and a multiplication sign. This is something that can be avoided by using something like the asterisk symbol to indicate multiplication.

Anyways, notice how the expression $3^x*2^{2x}+1$ shows up twice. Once in the numerator (the entire numerator) and once again in the denominator (nearly the whole thing)

Let's replace that messy expression with the variable y. So we're letting $y = 3^x*2^x+1$

This means,

$\frac{3^x*2^2+1}{3^x\left(3^x*2^2+1\right)} = \frac{y}{3^x*y}$

At this point you can probably see how to get $\frac{1}{3^x}$ from here. The y terms cancel out when we divide leaving 1 up top and 3^x down below.

Which set of ordered pairs represents a function?

Nikitich [7]

Answer: B. {(-8,-2), (7,-2), (-9,2), (0,0)}
Explanation: A, C, and D all have a number in the x value that is repeated therefore making them not functions.
