Question

The coach of cricket team buys 3 bats and 6 balls for rupees 3900 later she buys another bat and 3 more balls of the same kind for rupees 1300 represent this situation algebraically and geometrically

Answer 1

let rate of bat = xRs.

and rate of ball = yRs.

3x+6y=3900----(i)

and x+3y=1300-----(ii)

or x=(1300−3y)

now equation (i) can be written as

3(1300−3y)+6y=3900

3900−9y+6y=3900

∴y=0

Ans:- x=1300

Answer 2

Step-by-step explanation:

Given:The coach of cricket team buys 3 bats and 6 balls for rupees 3900 later she buys another bat and 3 more balls of the same kind for rupees 1300.

To find :Represent this information algebraically and geometrically.

Solution:

Let coach pay x rupees for one bat

and y rupees for one ball.

Thus,

3 bats costs :3x rupees

6 balls costs: 6y rupees

So,

$\boxed{\bold{3x + 6y = 3900}}$

by the same way

1 bat costs :x rupees

3 balls costs: 3y rupees

So,

$\boxed{\bold{x + 3y = 1300 }}$

To draw graph:

1) 3x+6y=3900

Put x=0

3.0+6y=3900

y=3900/6

y=650

Point is (0,650)

put y=0

3x+6.0=3900

3x=3900

x=1300

Another point is (1300,0)

Mark these points on graph and draw the line.

2) x+3y=1300

Put x=0

0+3y=1300

y=1300/3

y=433.33

Point is (0,433.33)

put y=0

x+3.0=1300

x=1300

Another point is (1300,0)

Mark these points on graph and draw the line.

Final answer:

Representation of suitation algebraically is shown below

$\bold{\red{3x + 6y = 3900}} \\ \bold{\green{x + 3y = 1300}}$

Graph is attatched.

Hope it helps you.
