Additive inverse of x - 1 x is

Additive inverse for a rational number is the same number with the opposite sign. Also, adding its additive inverse to a number results in zero. Additive inverse of a number is a number which when added to the given number gives zero. Let additive inverse of x - 1 x is f x . So, x - 1 x + f x = 0 ⇒ f x = 1 x - x Therefore, Additive inverse of x - 1 x is 1 x - x .

Find the product, using suitable property: 26 × ( - 48 ) + ( - 48 ) × ( - 36 )

The Distributive Property of Multiplication over Addition of Integers states that: For any three integers a , b and c , a × b + a × c = a × b + c Here, a = - 48 , b = 26 , c = - 36 ∴ 26 × ( - 48 ) + ( - 48 ) × ( - 36 ) = - 48 × 26 + ( - 36 ) = - 48 × ( - 10 ) = 480 Hence, the required product is 480 .

Find the value of the following: 81265 × 169 - 81265 × 69

Given, 81265 × 169 - 81265 × 69 We know that when a, b and c are whole numbers then by distributive property, a × b - c = a × b - a × c Here a = 81 , 265 ; b = 169 ; c = 69 81265 × 169 - 81265 × 69 = 81265 169 - 69 = 81265 × 100 Hence, 81265 × 169 - 81265 × 69 = 81 , 26 , 500 .

If a = − 8 , b = − 7 , c = 6 , verify that ( a + b ) + c = a + ( b + c ) .

Given, a = − 8 , b = − 7 , c = 6 , To verify that ( a + b ) + c = a + ( b + c ) . Consider LHS, ( a + b ) + c Now, put the values, we get: = ( − 8 + ( − 7 ) ) + 6 = − 15 + 6 = − 9 Similarly, Consider RHS: a + ( b + c ) Now, put the values, we get: = − 8 + ( − 7 + 6 ) = − 8 + ( − 1 ) = − 9 Therefore, LHS = - 9 = RHS Hence, verified. This also satisfies the property of associativity of addition.

Verify: 18 × [ 7 + ( - 3 ) ] = [ 18 × 7 ] + 18 × - 3

Given statement is : 18 × [ 7 + ( - 3 ) ] = [ 18 × 7 ] + [ 18 × ( - 3 ) ] Simplifying the LHS: 18 × [ 7 + ( - 3 ) ] = 18 × 4 = 72 Simplifying the RHS: [ 18 × 7 ] + [ 18 × ( - 3 ) ] = 126 + ( - 54 ) = 72 Since, L H S = R H S . Hence, the given statement is verified.

Write five pairs of integers ( a , b ) such that a ÷ b = - 3 . One such pair is ( 6 , - 2 ) because 6 ÷ ( - 2 ) = ( - 3 ) .

Five pairs of integers ( a , b ) such that a ÷ b = - 3 can be: (i) - 9 , 3 because - 9 ÷ 3 = - 3 (ii) 12 , - 4 because 12 ÷ - 4 = - 3 (iii) - 21 , 7 because - 21 ÷ 7 = - 3 (iv) 3 , - 1 because 3 ÷ - 1 = - 3 (v) - 15 , 5 because - 15 ÷ 5 = - 3

Find the following products: 9 × ( - 3 ) × ( - 6 )

Given: 9 × ( - 3 ) × ( - 6 ) We know that, The product of two integers of opposite signs is equal to the additive inverse of the product of their absolute values. The product of two integers with like signs is equal to the product of their absolute values. So, 9 × ( 3 ) = - 27 Therefore, - 27 × ( - 6 ) = + 162 Therefore, 9 × ( - 3 ) × ( - 6 ) = 162
