Answer 1

ANSWER;

1. ( a ) -5 × -3 = 15

8 7 56

Multiplicative inverse ;

15 = 56

56 15

Multiplicative inverse of 15 is 56

56 15

( b ) 19 = - 19

13 13

Multiplicative inverse ;

- 19 = 13

13 - 19

Multiplicative inverse of - 19 is 13

13 - 19

2. ( a ) x - 7 = 9

x = 9 + 7

x = 16

( b ) m = 10

5

m = 10 × 5

m = 50
