Answer:

The answer is 108.

Step-by-step explanation:

This can be solved with a simple proportion. 5/12 = 45/1. For 5 to become 45, you need to multiply by 9. You do the same to the denominator. 12 times 9 is 108.

If we divide Rs 20 between Jatin and Arnav in the ratio 3 : 2, how much will each of<br> them get?
Papessa [141]

Answer:

$12

$8

Step-by-step explanation:

Amount Jatin received = (ratio of Jatin's share / sum of ratios) x amount shared

sum of ratios = 3 + 2 = 5

(3/5) x 20 = $12

Amount Arnav received = (ratio of Arnav's share / sum of ratios) x amount shared

(2/5) x 20 = $8

or

$20 - $12 = $8

The length of a rectangle is 3 units shorter than one-third of the width, x.
AveGali [126]

\frac{8x}{3} - 6 is the expression that represents the perimeter of rectangle

<em><u>Solution:</u></em>

Let "x" represent the width of rectangle

Given that length of rectangle is 3 units shorter than one-third of the width x

length of rectangle = one-third of the width x - 3

\text{ length of rectangle} = \frac{1}{3}x - 3 = \frac{x}{3} - 3\\\\\text{ length of rectangle} = \frac{x}{3} - 3

<em><u>The perimeter of rectangle is given as:</u></em>

<h3>perimeter of rectangle = 2(length + width)</h3>

Substituting the known values we get,

\text{ perimeter of rectangle }= 2(\frac{x}{3} - 3 + x)\\\\\rightarrow 2(\frac{x - 9 + 3x}{3})\\\\\rightarrow 2(\frac{4x-9}{3})\\\\\rightarrow\frac{8x-18}{3}\\\\\rightarrow\frac{8x}{3} - \frac{18}{3}\\\\\rightarrow\frac{8x}{3} - 6

Thus perimeter of rectangle is \frac{8x}{3} - 6

Thus option 1 is correct
