Question

7. Find 34 - (-72) and (-72) - 34. Are they equal?
8. The sum of two integers is -13. If one of the numbers is 170, find the other.
9. The sum of two integers is 65. If one of the integers is -47, find the other.​

Answer 1

Answer:

(7.) 34 - (-72)

34 + 73

106 ans

(-72) - 34

-73 -34

-106

therefore, they are not equal

(8.) the sum of two integer= -13

one of other integer = - 72

= x - 13 = -72

= x = -13 + (-72)

= x = -13 -72

= x = -55 ans

= the other integer is -55 .

(9.) the sum of two integer = -65

one of the other integer = -47

= x -65 = - 47

= x = -65 -47

= x = -112 ans

= the other integer is -112
