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)

Arisa [49]

Answer:

at least three are dimes

so we have 20 coins with a total of 3.50

if the rest are all quarters then there would be 4*3+2=14 but we need 20

so we are 6 short

we must have dimes in multiples of 5

12 q + 5 d=3.50 but only 17 coins

10q +10 dimes=3.50 with 20 coins

10 q +13 dimes total

algebraic solution

d+q=23

25q+10d=380

d=23-q

What is the slope of the line through (3, 2) and (-3,4)?

Andre45 [30]

Answer:

Choice A. -3

Step-by-step explanation:

Using the x1-x2/ y1-y2 u fill in. So it would be 3-(-3) (x-axis) and 2-4 (y-axis).

So when u do both of those you are left with 6/-2.

When u simplify 6/-2 you get -3.
