Question

What is answer this one ​

Answer 1

Answer:

Step-by-step explanation:

Which one

8. { -13 - (-27)} + {-25 - (-40) }

= { -13 + 27 } + (-25 + 40}

= 14 + ( 15)

= 29

9. 36 - (-64) and (-64) - 36 are not same

36 - (-64) = 36 + 64 = 100

-64 - 36 = -100

So both are different

Answer 2

Answer:

Step-by-step explanation:

8){-13-(-27)} + {-25-(-40)}

= {-13 + 27} + {-25+40}

={14} + {15}

={29}    (ans)

9) 36 + 64  and  -64-36

= 100   is not equal to -100

10) a=8,b=7 and c=6

then,

(a+b)+c=a+(b+c)

(8+7)+6 = 8+(7+6)

(15)+6 = 8 + (13)

21 = 21

so both are equal

11) a=-9 and b=-6

(a-b)

= -9 + 6

= -3

b-a

=-6 + 9

=3

so they are not equal

12)so let the missing integer be x

so,

53+x = -16

x = -16-53

x=69

so the missing integer is 69

13)let the missing integer be x

so,

x+(-31) = 65

x-31=65

x=65+31

x=96

14)so,

a - (-6) = 4

a+6=4

a=4-6

a= -2

for question 15 you can follow the hints which are given.

hope it will help you and please mark as the brainliest :)
