Answer 1

Answer:

Solution 1:

The larger of two supplementary angles exceeds the smaller by 18°.

The angles.

Let the two angles be r° and m°.

We know that supplementary angle be 180°

A/q

&

So;

Putting the value of r in equation (1),we get;

Putting the value of m in equation (2),we get;

Thus;

The angles are r = 99° and m = 81° .

Solution 2:

The coach of a cricket team buys 7 bats and 6 balls for 3800.Later, she buys 3 bats and 5 balls for Rs.1750.Find the cost of each bats and each balls.

Let the cost of one bat be Rs.r

Let the cost of one ball be Rs.m

So, the equation formed, we get;

From equation (1),we get;

Putting the value of r in equation (2),we get;

Putting the value of m in equation (3),we get;

Thus;

The cost of one bat be Rs.500.

The cost of one ball be Rs.50.
