Answer:
The answer is
10. hence verified
11. hence verified
12. The other number is -69
13. the other number is 96
Step-by-step explanation:
10.
TO verify(a + b) + c = a + (b + c)
Step 1 = According to the question,
A = -8, B = -7, C = 6(given)
Step 2 = Follow the equation given in the question
(a + b) + c = a + (b + c)
[(-8) + (-7)] + 6 = -8 + [(-7) + 6)]
-15 + 6 = -8 + (-1)
-9 = -9
HENCE VERIFIED
11.
To verify (a - b) is not equal to (b - a)
Step 1 = According to the question,
A = -9, B = -6
Step 2 = Follow the equation given in the question
(a - b) is not equal to (b - a)
[(-9) - (-6)] is not equal to [(-6) - (-9)]
(-9 + 6) is not equal to (-6 + 9)
(-3) is not equal to (3)
HENCE VERIFIED
12.
To find the other number
Step 1 = Let the other number(integer) be x
According to the question,
The sum of two integers is -16(given).If one of the number is 53(given).
Step 2 = Equate the addition of two integers and their answer(-16)
That is,
53 + x = -16
x = -16 - 53
= -69(The other number[integer])
13.
To find the other number
Step 1 = Let the other number(integer) be x
According to the question,
The sum of two integers is 65(given).If one of the number is -31(given).
Step 2 = Equate the addition of two integers and their answer(65)
That is,
-31 + x = 65
x = 65 + 31
= 96(The other number[integer])
